    3.8l VT hesitation / misfire under light load when warm

    Well. The mechanic has rung me back with good news the car is running fine and all fixed and running fine. he says that No3 and No5 plug leads were not 100% clipped on causing them to short the plugs out intermittently when the engine moves during acceleration! No 5 lead was a bit tight when...

    3.8l VT hesitation / misfire under light load when warm

    So, Ive had to give up on this myself and have dropped it off to a local mechanic to see what he can find. If he comes back with an answer, ill update here to let people know

    Thanks Lex for the tips - really appreciate the effort. Ive got to head off to the fire shed for our friday night meet, so no more work for now. The plugs and leads are all new (last 500km) - but will inspect them either later tonight or tomorrow morning for sludging or blackness Ill also...

    3.8l VT hesitation / misfire under light load when warm

    I checked this early on in the piece. I just checked it again, and decided that ill replace the hose as it was looking a bit shabby. But no signs of fuel leaking back into the vacuum hose and into the intake manifold. Also just sprayed brake cleaner around the seal joins again, looking for a...

    3.8l VT hesitation / misfire under light load when warm

    Ok, so next update. have got the wire sorted out. Its all happy again now. back to starting normally. But now back to where i started over 2 weeks ago. Speaking with a mechanic friend (in between his jobs at work) he has been looking at the o2 sensor readings and long term fuel trims. o2...

    3.8l VT hesitation / misfire under light load when warm

    So I have finally got off shift and now have time to look at this again Pulled the dfi plug and found the second wire (white with black trace) has been pushed back. (N= ICM (+10v)) So managed to push the pin back in, but it seems the little locking tabs inside are worn - so I think the pin...

    V5025 - thanks - yep got the harmonic balancer back on - issue sorted. But the real problem is still finding ways to confound me. Its now even harder to start than before - so its gotten worse. At least before it started easy enough, so it struggles to start, and i've got to hold the throttle...

    3.8l VT hesitation / misfire under light load when warm

    So I go to start it this morning and it wont budge. Bloody thing will fire once, then fail to hold idle. I give up and get a lift to the fire station for todays shift. grrr.. So after todays shift on the fire ground I go back under the bonnet again - some google research suggests that its the...

    3.8l VT hesitation / misfire under light load when warm

    Thanks Kyle_au for your info. I went and caught up with a friend who runs a tool van and ive got a stumpy rattle gun thats good for 300nm. This, with a run up, 125psi and locktite and that should be fine. It pulled up great. I also changed the front oil seal while I was there. Update from...

    3.8l VT hesitation / misfire under light load when warm

    After I got back from the fire today, I had a few hours, so as we all know, jobs don't get done by sitting around - so to the shed.. Replaced the Throttle position sensor - no change Replaced the Idle air control - no change replaced the cam angle sensor - no change Pulled the crank bolt out...

    3.8l VT hesitation / misfire under light load when warm

    Thanks for getting back. I havent been able to do any work for the last week - been working. Have a couple of RDOs now till christmas. Pulled the injectors this morning and 'serviced' them. (new o-rings, filter baskets, pintle caps) and ran brake cleaner through them whilst pulsing the...

    3.8l VT hesitation / misfire under light load when warm

    Well it all seems a moot point. No parts (TPS, IAC or Injector service kits) available in Perth according to Repco, Auto One and Autopro. Ive placed an order (TPS and injector kit) and will just drive it in the mean time. Expect to get the parts in the next 3-5 days. Once fitted, ill update if...

    I haven't done it before - but have heard of this. Would this give me different codes that a odb2 reader. I use a laptop and the software from Envious Customs. Advanced Engine Diagnostics / Software on Elm St I dont get any error codes from this. Im about to go down and buy a Throttle...

    3.8l VT hesitation / misfire under light load when warm

    Glued up the plenum to runners face with No3 (non-hardening) aviation gasket glue - no change. - man that shiz is messy. its still doing the drop in revs at idle every so often. I'm still suspecting a vacuum leak somewhere, but I'm running out of things to check. All the hose seem intact, and...

    3.8l VT hesitation / misfire under light load when warm

    so sprayed brake cleaner around anything i could get to - No changes that i could find, but i wasn't expecting anything as its idling fine. Slow ,controlled acceleration everything seems to be fine. Only when you give it a foot-full does it do its miss thing. rechecked the coils - they seem to...

    3.8l VT hesitation / misfire under light load when warm

    so, just got everything back together and took it for a test run. no dice - still playing up. its def running better and smoother, but its still doing the 'half-a-miss' thing when accelerating. Runs fine at idle. about to try the 'spray flammable stuff' at the gaskets and flanges to see if...

    3.8l VT hesitation / misfire under light load when warm

    Updates The bolts in the valley, some were milky, so some water has been mixing in with the oil, but not enough to notice it seems. The black grime on the inside of the plenum, feels gritty. Hope thats just carbon, and not sand..... Have just got the bolts out, and going to get the tensioner...

    They were only done 500km ago. NGK units. Shouldn't need to do them yet!. When i go to the shop, ill buy a service kit anyways so that I have stock at home. 2001 Series II VT Wagon. Ill double check to make sure that I get the right ones - and make sure that I get a complete upper set. Ill...

    3.8l VT hesitation / misfire under light load when warm

    I've done what I can with the FPR. there doesn't appear fuel leaking into the vacuum hose so I think that the diaphragm is fine (ie not split). Its strange. It idles fine ( aside from the random drop in revs every so often), it revs up fine if you do it slowly, but give the pedal a stab, and it...

    3.8l VT hesitation / misfire under light load when warm

    Thank Lex I have 2 spare DFi units here in the shed - none of them have improved the outcome. Repco have a special on these at the moment (https://www.repco.com.au/parts-service/ignition/car-ignition-modules/fuelmiser-ignition-module-cm414/p/A8784387) Have just had a look under the car again...

    3.8l VT hesitation / misfire under light load when warm

    Well it seems that my success was short lived - bugger. Its been back to its usual games now for the last 2 weeks. I'm only now got time to get to it. When I bring the engine idle up slowly, its runs fine all the way to redline. If I stab the throttle, its starts its missing caper, running...

    3.8l VT hesitation / misfire under light load when warm

    So, Last weekend, i went and purchased a set of ignition leads from my local auto store. I was surprised at the cost, ($120) but I wanted to resolve the issue, so hand over the folding, and off I go. After some cursing that I have to remove the alternator to the get the leads out and back...

    Hi Folks Car is VT 2001 Executive wagon 3.8l , 340km - and showing every km on it - its hard a hard life I think before it came to me in 2016. The engine is very tired, but performs just fine for its intended purpose. The car is just a hack , but it still deserves some basic maintenance. It...

    Holden Paint code conundrum

    The most annoying part about this is that I bought a can of paint from the same store about 3 years ago to paint up the fibreglass shroud under the bullbar. A light sand, 1 coat of plastic primer, 1 can of paint, 1 can of clear topcoat - been perfect for 3 years now. At that point, the guy at...

    @Whiteshark68 - i agree. I call the shop again tomorrow and ask them about the Tungsten Mica and see if that helps them. Thanks for the info folks - appreciate it

    Holden Paint code conundrum

    Thanks, but that just makes it more confusing! Dang nam it..... My car, according to the VIN is a 2000 model, listed as a 2001 model on the papers - It must have been sold in 2001, but made in 2000. Its a series II as far as I can tell. The paint shop guy said that the VIN number doesn't help...

    Holden Paint code conundrum

    Hi Folks I am about to paint a new fuel flap on my MY2000 VT commodore executive wagon. I take the paint code to my local Auto one to mix up a spray pack - H114 Tungsten, and the guy comes back saying that there is two different mixes for that code - one is lighter than the other. The lighter...

    heater control and headlight control lights - U/S

    Thanks for the diagram. I was hoping that there might be a fix less arduous than that. I'm not bad with a test light, but i'm no auto sparky either. Ill print these out and see if anything comes from it and post back when I do.

    heater control and headlight control lights - U/S

    Ok, Thanks to the advice from folks here I worked out the leaking water issues, so perhaps I can get a win on this one to. So i have a niggly little issue that so far has eluded me. The lights that sit behind the heater controls and the headlight switch dont work. The indicator lights for the...

    Wet drivers side floor

    the door seal that sits against the window , is that called the weather strip? As in would this be suitable for a 2001 VT II wagon https://www.ebay.com.au/itm/4pcs-Weatherstrips-Weather-Strips-FOR-Holden-commodore-VT-VX-VY-VZ-SEDAN-HSV/254347984929 or this sort of thing? as it seems my car...

    Wet drivers side floor

    So, I tried to find the leak again and.... success! After running the hose on specific areas for about 20 minutes I found two leaks. 1 massive one - which explains the sodden carpet 1 small one, which i think explains the water in rubber floor mat (I hope) The small one is under the dash...

    Wet drivers side floor

    Ok, apologies for the necromancy, but... So it turns out that its not the door seal - I have picked up my car from my mums place, where it has been parked for a week. We had that rain last week in Perth, about 25mm by mums estimate and my car is parked in the open. the next day, mum checked...

    VZ 2100kg towbar

    Anyone got any feedback? If I can just but a 2100kg bar from anything between 99-2005 (VT-VZ) then its a much easier process to find a second hand unit. Ill also be fitting a tranny cooler, so if I can find a genuine towbar with genuine towing kit installed, then Ill steal that as well.

    VZ 2100kg towbar

    Hi Folks Im looking to fit a second hand 2100kg towbar to the VZ wagon (2005), and my initial searches have not yet turned up one. Plenty of the lighter duty units about but no 2100kg ones so far. In order to widen the search, will the 2100kg units from VT-VZ fit? Ive seen some 2100kg units...

    Wet drivers side floor

    Losh1971, I took your advice and the trouble and strife is picking up a tube for me today. I got the windscreen seal out and scrubbed clean everything - geez that was filthy. Next i got the hose on jet stream and squirted directly into the exposed windscreen edge (sans seal) to see if i can...

    Wet drivers side floor

    Ok so a further update. I have spent the last 3 days drying out the carpet. I even spent the time to re-lay the sound proofing seal stuff with my heat gun. (after the beat out the dent in the floor pan, the proofing stuff came loose and broke apart). I nicked some old stuff from a wrecked...

    Wet drivers side floor

    Thats what I was thinking - The old dunnydore certainly isnt a princess, but im not that mean to it. I guessing that the water thats getting into the front is tracking back slowly to the behind the seat once the front area was full. I pulled the seat this arvo and will let it dry tomorrow. On...
