It's not their problem and they don't get paid to do that, but they get paid when the car comes back for a re-inspection.

That's true, but oil & filter change very other service.

Yes I did that on all the ebay coils (4 pin) all coils gave the same results - O ohm on 2 pins, infinity on another two and about 12,000 on another two pins, including the coil that gave the intermittent misfire.

Don't try or it will be bin fodder.

Update: 2-3 years ago I was coming home from the local shops when the donk developed a misfire. By the time I got to within 100m of home it was running on 3 cyls.. When I pulled into the driveway and switched off, smoke began to emanate from under the bonnet. This is what I found after I...

Driving home from Perth on Friday (420km trip) my VZ V6 developed an intermittent miss under load and at idle. It was ok at 110kph on the flat but would miss going up hill. On Saturday I replaced the Denso Iridium plugs with AC Delco Platinum plugs. The Denso set had done 110,000km so was a bit...

I'm struggling to take it out. I had the same issue. There's a description earlier on in this thread of how to make a puller/slide hammer to get it out.

Probly known by others but the first I've seen these specific details. http://australiancar.reviews/holden_LE0.php

You're mad!

Mine checked out ok, no cracks and still a bit soft. 288,000km

Thanks Fu. I'll check the hoses on mine tomorrow.

Checked for correct amount of refrigerant that's exactly spot on. How did you do that? Do the radiator fans come on soon after the compressor engages?

It solved my similar problem.

but he says it's running ok otherwise. Just curious.

Check the fuses yourself - it cost nothing, like Fu says.

There are separate fuses for L & R cyl bank. - check them.

But it may allow it to start if in D or R - better check.

As I said in reply 21, my VZ V6 was doing similar things. Yesdy I fitted a new oil pressure sensor, which seems to have fixed it. When I removed the harness plug from the sensor it was a bit oily - obviously beginning to leak.

A few days ago I cleaned some of the earths as suggested. I didn't get into the one under the wiper cowl yet and I couldn't locate the one at rear of left cyl head - may need a small mirror. The one below the ABS unit where the battery and harness are earthed seemed to be the culprit - nothing...

He's talking metric, not PSI = 25-30psi

Oil pressure showed 217kpa - was that hot or cold, idling or at revs? I have a similar issue on my V6 and am about to make an adapter to fit a test gauge to get actually readings before l pull anything apart.

See my slightly different issue from reply 9. https://forums.justcommodores.com.au/threads/vz-sv6-problems.144075/

My VZ V6 does the same thing SVS and Check Oil Level and has done so on and off for a year - happens about 8-10 min after starting and disappear after a few seconds. Nothing to reset! OP sensor replacement made no change. It happens most days but not every day.

Thanks Fu - will do.

Thanks fellas. I checked battery earth and stater cables today - both good and tight. I'm not happy with 9v but 10 should be ok when cranking but I'll probly get a new battery in the next week or 2. I'll clean the battery earth under the alternator within the next day or so. Where are other...

Well, that didn't fix it. It cut out immediately after starting on the second start of the day after sitting for an hour. I checked battery while starting; about 9.2v - switched off and restarted ok showed about 8.8v but it started and kept running. Checked again 30min later - 10.2 v while...

I did some more thorough checking of vac connections today and found this: One of the 2 PCV lines into the manifold. If replacement has solved the problem I'll take back all the tasty stuff I thought about you blokes who said vacuum leak. :p I'll let youz know in a week. :)

Thanks Kruzing - I'll do some more checking of connections. I did the PCV valve mod before Xmas and fitted a new fuel pump a few weeks ago but the issue started after I'd recently since done 2000km towing a camper trailer. The car runs perfectly otherwise and the fuel filter was replaced about...

Haven't got the equipment yet to do a smoke test but here's an update on the issue in which the eng would intermittently cut out a couple of seconds after firing up as normal when warm; a few days ago after it did that, I turned key to off, waited a couple of seconds and tried to re-start but...

It runs perfectly when hot. I haven't tried restarting it when hot, just an hour or 3 later. I might do a Kodak on it and see what develops.

Old thread but new issue for me on 3.6 VZ auto wagon (not SV6). It's done 278k km. In the last couple of days when I start the engine it fires up normally but then dies within a few seconds. It's done it only 3 or 4 times over 2 days and not the first start for the day, so warm engine. It...

You're right P. I replaced the pump and broke the old one apart to check it's innards. The middle one of the 3 connectors was a mongrel to release due to the other 2 pipes restricting access to the release buttons. 3 hours from start to finish, which included syphoning 40 L of fuel from the...

Dunno, but it sounds serious. Any other issues with it apart from message?

Where did you get the Schaeffer kit from T?

Where did you get the Schaeffer kit from T?

Can't you use a drill bit from the opposite end to remove it and push out? Then flush and blow out.

Hmmm. Ryco show a Z586 in-line which I replace periodically and a Z1148 in-tank fuel filter for my car. Repco show a complete pump assembly FPE417. I'll probly just that when I can work meself up to dropping the tank.
