VZ SV6 running like a pig

Is there anyway to test the coils? And how much are they?

hey guys took the car to an auto electrician today. he put the scanner on the car and it came up with #2 fuel injector fault. He told me how to do a few quick checks on the fuel injector to see if its faulty electrical wise. He thinks if the injector looks ok it will be the ECM and only Holden can install them and at a price of $900 dollars just for the part and not the installation hopefully I will be able to get an aftermarket ECM.

I had the same thing wrong with my car spent about 4 months in and out of mechanics and automotive specialists. Had ECM, BCM replaced, sparks replaced at least 3 or 4 times, replaced all connections. Turns out it was one of the coils but every time I had one that was supposed to be faulty replaced another would die on me, all up cost me around about $5000 to fix. (Coils were about $200 including labour per fitting) Not cheap I recommend you get your coils/coil pack checked!!
Good Luck!

Maybe you should sell it and Buy a SS???

HFV6 coils manufactured between 8 May and 10 May 2004 are known to fail prematurely. Check the date on your coils and replace if affected. They have the date printed on the side - if you have any with "04-05-08", "04-05-09" or "04-05-10" then that's quite likely your problem.

My coils were not within this range but were still faulty... so they are still worthwhile checking.

I have had it confirmed from a holden employee that these will need to be replaced eventually.

Instead of spending $5000 like the unlucky bloke above, here is an alternative solution.

Buy these: GENUINE HOLDEN COMMODORE VZ V6 BOSCH COILS 3.6L - eBay, Other Car Parts, Accessories, Car Parts, Accessories, Cars, Bikes, Boats. (end time 02-Jan-10 11:38:52 AEDST)

And replace them yourself (let me know if you would like some advice - but its pretty simple) If you get this done by holden, you'll end up paying around $150 per coil to get them replaced, so just get the whole lot done for the same price by buying them online.

In a worst case scenario that this does not solve your problem, you'll know coils are not going to cause any problems in the future. Based on how common they seem to be failing it seems like a smart move to me. :idea:

I've got a guy i work with who has a 2006 sv6 and his car missfires aswell?? usually when it's cold and he's driving along at about 100 it'll seem like it's missing.. does it often n holden 'claim' they don't know whats wrong with it..

 

[MrNathanSV6]

Well I narrowed down this mis to No.2 cylinder. I replaced the coil pack today for that cylinder but it made know difference at all. Maybe the injector?

 

[MrNathanSV6]

I swapped no1 and no2 injector over yesterday and still a miss in no2 cylinder. I am stumped now
