Great outcome! Excellent fitout too.

Which we all know shouldn't be the case. As far as I know, the alternator has the voltage regulator built in. Given your situation, I'd be using a multi meter to measure between the chassis and the output terminal on the alternator. Then, if it is over voltage (more than +14 v at a guess) I...

I can't explain why all of the relays would be hot collectively assuming there is no nearby heat source. The overcharging and whatnot - have you checked the engine and battery are grounded properly?

Maybe get a scanner on there first, Phil, before taking apart.

Keep us posted :)

I think it was plane driver who provided the link, and yes the sticky indicator/s is really common. Mine hasn't gone yet luckily. I had a few things contributing to rough idle, all caused by a careless mechanic at Holden: 1. One coil was inserted poorly, resulting in a pinched rubber seal, which...

Sounds like you have nailed the issue. I'm assuming you have removed and reattached the two connectors from the ECU? Maybe get a second hand ECU installed and coded to your car...Saves a lot of hassle trying to fix it.

A big worry is the apparent absence of oil from when you bought it. It may not have been as low as you thought, if the Oil warning light only came on after driving 100 kms. You have the 'mild diesel' sound coming and going - Maybe oil pump? Blocked sump oil pickup? Engine sludge? You may want to...

Any luck? How did you go?

Thanks so much. I'll do this in future - it was an annoying little problem

Hi all, been busy with things lately and haven't checked in on this thread in some months. My VZ is still running fairly smooth since I replaced the coils. Idle improved a little more after I cleaned the throttle body and MAF (the MAF cleaner was quite expensive, but is a must for cleaning MAF...

Mine has one (V6 3.6 LE0), and it needs replacing because it has been pinched out of shape..

Chris that's great news mate! Happy motoring!

What a pearler of a fix. I'll keep it in mind for later use if needed. Thanks and Happy New Year!

I know nothing about the model but in terms of the malfunction, I'd be inclined to spray contact cleaner (not WD40) into the switch in case it's just dirty contacts.

How are you going with this. Happy New Year too :)

It won't cost much, good idea. Give the thing a wriggle yourself and see if you can get it to knock. How are your engine mounts? Also the spring rubbers at the bottoms of your coil springs?

You mentioned the exhaust. What was the outcome of that?

Interesting discussion. I find the battery strap a problem for checking the water levels. On my old Century battery, the top flap of the battery had to swing open to reveal the filler caps. Battery strap would have been in the way, perhaps this might be why Holden changed it. I have a no...

Hi Dandy2012. Sedan or Wagon?

FYI to those who need it.

Hi everyone, Had a problem last week with starting. There was only a 'click' from the starter when I turned the key - but everything else seemed fine (radio, lights etc). I then tried a spare battery I have, no issues, so it looks like the problem is solved. On checking I found the battery...

Some great advice here, but my pick would be simply to bleed the radiator from the screw and put on a new radiator cap. You might be pleasantly surprised. If not, then it's cost you very little. Noisy water pump will be functional for a short time so you should look to replace it regardless of...

Don't be casual about routine servicing. It really important. If you need oil and fluids done then do it.

Shelly From memory the plugs go around 120K. You can change them, just get the right socket and extension and you will be fine.

No worries Shelly, you are welcome. Good advice. Yes Shelly, change the auto oil. Good call. Noise coming from gearbox not a great thing, but change of oil will do no damage. Go easy on it until it's fixed. My bad idle issue never threw up a trouble code, not even with a faulty coil. Coils...

Hi Shelly, What is the mileage on your car, and the build date? How does it idle? Does it miss when you give it a bit of a rev in park? Okay if you are worried about your transmission, how does the transmission oil look? Is it a reddish colour or dark brown? The transmissions are pretty tough...

Hi and welcome, Shelly. If you have the rough idle problem. you'll want to work through systematically. First get it checked for trouble codes. If there's nothing, then check your vacuum hoses for cracks etc. If they are okay, check fuel filter is not blocked (replace it if it's old) and then...

I tend to use 5W-30 Oil, which might help you.

Looks about right - try using 98 ULP if you are not already doing so.

Crowny if your plugs aren't that old then leave them they should be fine. Up to you if you change your coils, I bought a set of six genuine Bosch off eBay for $350 including the replacement gaskets (which weren't really needed, mine were fine). If you take the plenum off, take your time with all...

Hi Crowny, yes it did. Have you had your plugs done yet?

Still going great. So happy to have my car running properly again.

Hi Fu Manchu Great thread. Just a comment on one of your images where you mention wires fused together. The TPS is a variable resistor and those little groups of fingers are called 'wipers'. Each group of fingers is actually one conductor, so it is okay if they 'touch'. But they should not be...

Hi Fu Manchu I couldn't agree more on finishing what's been started - I always try to follow through. I hope it helps someone. This forum has saved me a lot of money a couple of times over. Have a great day mate.

Putting something under the wheels is a great idea, I hadn't thought of that in my adventure. Of course in my case, the bumper had come away, and I was 'free' so to speak :)

I dislodge my bumper on a pallet, but was able to just snap it back into position by hand.

Hi All, Posted a while ago about my rough idle issue. Had the ECU replaced which did not fix the issue. Turns out one coil had not been installed properly by the technicians at Holden. The rubber seal was damaged and let water in, which corroded the coil shaft and presumably the internal...

After putting up with rough idle for a year (trembling) I have just replaced the coils this afternoon. One of the rubber boots was damaged and had let water in, totally corroding it. Cost $350 for a set of six with a set of inlet gaskets. Job took half an ahour and I have very little mechanical...
