After all the fault finding/fixing, have you reset the ecu? Sometimes a relearn fixes head scratchers

JHP GTS type intake, exhaust, it has more pull midrange and I think the redline is 6500

ok so engine was cold but I disconnected the MAF plug and no code...

surprised this is not stuck somewhere, is is easy enough to search... Engine Control Unit Diagnostic Test TO CHECK ERROR CODES: 1. remove screw retaining the passenger side kick panel 2. turn the diagnostic mode selector fully clockwise to diagnostic 3. start the engine and let it idle 4. watch...

yeah that's what I am looking for, will try this today as I was told it's 300kw tune but it feels almost the same as my 245kw SV8, surly I would feel 50 odd extra KW difference...

so could I see that via the OBDII with ELM327 or what? Say, if it has MAF on the engine but the tune is MAFLESS?

Looks like I will be off to the dyno, maybe after I change the final drive...

Have MAF and mods, don't care about power, just want some information on how to identify what tune I have, whether it be MAF or MAFLESS, 300KW or 245KW or 235KW etc etc

How can I tell if my VY PCM has the standard tune or the 300kw tune?

Would the pedal come good then drop to nothing again if the ABS is dead? It's all dead stock.

Yes I think there is air still in the system (ABS), I don't have access to Tech 1 to purge it so will try vacuum bleeding on the weekend.

Yep, bench bled, but I don't have those plastic blank bolts and lost a little fluid as I fitted it.

Hope someone can help me, I fitted a new M/C after a gradual fail and after finally getting a good pedal on the bleed (altho I wasn't 100% happy with the bleed, I did get a good pedal) I lost all pedal after 40min drive. I have bled brakes for decades and usually don't have a problem, have I...

My hand brake has broken for the second time after my repair. After reading quite a few threads back then, I decided to glue it. The bond has failed, I am wondering if anyone has replaced it with the VY type that has a metal rod. If you have had one fail you know what I mean.

I started testing and isolating and turns out the radio had the fault. Disconnected and now everything is back to normal :cool: Good excuse to fit that Pioneer I've had sitting there.

I've hooked the battery up the wrong way, now it is right I have found fuse one (under the steering wheel) for "parking lamps, trip computer, radio, power antenna." keeps blowing, like there is a short somewhere, can not even put the fuse in without it arching. I'm thinking it has something to...

89 year old Ron Chester was stopped by the police around 2 a.m. and was asked where he was going at that time of night. Ron replied, "I'm on my way to a lecture about alcohol abuse and the effects it has on the human body, as well as smoking and staying out late." The officer asked, "Really...

Fuel pump?

Do a cylinder balance test, at running temp, disconnect one injector at a time and see if you get a change in idle for each cylinder.

I'm thinking along the lines of woteva and am going to lube the bushes and go from there.

Be aware that some coolant brands and types don't mix even if they are the same colour...

Had a pump go, and very slowly, would let me down when hot then start up again after cooling, also had the return to the swirl pot break away, starves for fuel on low tank level.

My IRS makes a groan when I get out the car, anyone tell me what it could be?

I think you can just buy a roll of braid and the end covers and cut to size and fit over your existing hose, hose restoration/hot rod shops sell the kits etc

Trying to help a mate, Does anyone have any info on DTC 02 Instantaneous Battery Voltage Out of Range

Been there, done that. Can't clamp off the nylon lines to test further back. Need Holdens test procedure...

Hey having a hell of a time diagnosing my LS1 fuel problems, does anyone have a copy of Holdens test procedure for fuel system?

I have spoken to one mechanic whom tried selling me a damper claiming it would fix the issues. Now idle stumble, and reverse stumble are creeping back in again. today, I hit the track and at about 160 the car seemed to slow, I really expected to see 200 when I looked at the speedo. I Am getting...

Yeah but do you even read bro? Im on my third fuel reg...

It's a complete module I have been replacing in the tank, sorry for any confusion using the wording "fuel pump", it's an omission form an old school guy... There is no issue with the injectors.

Im not keen to clamp off the two nylon lines at the tank to test the pump return valve and reg. Any suggestions or does anyone have a copy of Holdens test procedure?

I'm on my third pump now, two returned to AFI and now the third Delphi is also losing pressure and causing hard start issues. Anyone got some experiences to share? Thinking of installing non return valve in line...

Could be the IAC as I squirted the TB a few days ago, seems to have settled down again. Is there replacement IAC valves available separately?

Last few days the throttle drive on the passenger side fire wall is clicking (energizing) when I key the ignition on to start the engine. What could be wrong with it (or the throttle body)?

After doing a bit more reading it may even be a faulty pump. Far out, car will be off the road for weeks while they send it back for testing...

V8 heater tap just lays on top drivers side front of manifold, under the drivers side engine cover if you have them. Some after market taps are different shape to OEM and will require some maneuvering to get them to sit nice under the cover.

Replaced my fuel pump and it fixed most everything but within days the hard starting crept back in, one month later I installed a gauge on the rail, clamp the fuel line after shut down and pressure holds, take the clamp off and pressure drops about 10psi almost immediately. Spare parts want me...

Check A; B+ connection at rear of alternator is clean and tight and not burnt out And B; battery connections are clean and tight, C; Battery is good, And D; All earth cables are present and secure.

a lot goes wrong with a car when service intervals are ignored, best sell it and buy a car that has been maintained correctly, or, start learning how to maintain a car yourself.

Any mechanic worth his wage has a vacuum pump...
