Anyone had faulty Coil packs?

[Guest Robo's]

I just changed my plugs and gapped them to .81 and its still misfiring up high, between 5500-6500, everywhere else is great. Turn the boost up and it just gets worse.

Would it be a coil pack, maybe i will just buy one and try them on each cylinder.

what boost are you running ?

You may have to run a smaller gap.

I have to run .5 to run 19 psi.

Try regaping ur plugs to either .5 or .6 and see how u go,if it still miss fires then test the coil packs one by one

i was experiencing the same problem...gapped new spark plugs to 0.9...same problem. Gapped them to a little less of 0.8 and no miss fire.

I had a misfire some time ago too. I had the plugs replace (gapped to 0.76) and it was still there. Turned out to be a dirty coil pack. The mechanic cleaned them up for me and it worked fine after that. I think he used electrical contact cleaner or carby cleaner - can't be sure.

Just found the problem, Coil pack, i slipped the boot off all of them and one of them has a nice old crack in it.

Now too get a new one

I have seen on a website, that the resistance for them should be around .7ohms. I tested mine and they were all 1.0ohm. I was told by an electrical supplier that they either work or they dont. Theres no in between. Theres, measured at .67ohms, (new).

There's (ACA) were O.E. type coil packs which relates to a genuine Nissan coil pack.

I also saw a R32 GTR manual and quoted the resistance to be between .6-.9 ohms.

ACA branded would be well over the $200 mark. Anyone priced a genuine Nissan one BTW???

Sorry to bring this up again... is that $200 price for each or a set of 6?

[T0nyGTSt]

You can usually get complete set for $250 or so from the wreckers???

[croat]

yeah cheap from the wreckers but they have been used and probably wearing near their life span and u will end up with the same problem that u started with, better just get new 1's.

250 from Dealer

[cobo_11]

$250 each? and from who? would they be ok to use with stock coil packs?

Iwas wondering is there anyway to check the coil pack with out taking them out.?

I have got the same problem with the missfire.And if it is a coil pack does anyone know where I can get a new one or second hand one for an R34 GTt.

I put new platium plugs in and the problem seems to have got worse.I will pull the plugs out and re check the gap.

[JimX]

$50 each second hand is the going rate for coils. Also, I think a gap of 0.5 or 0.6 is way too small for stock boost. Even 0.8 seems to be ok for up to around 14psi.

NIZR34GTT, the problem probably got worse with platinums because they have the weakest spark of all the plugs. It's probably just amplifying a problem with your coils.

[CWest]

Sorry late response. R34 coil packs new 250 from Nissan Dealer.

Second Hand 50 - 150. BTW R34 coil packs are same as R33 S2 coil packs.

Install them yourself if you can, I got ripped off charged 600 for coil pack and installation from Nissan Dealership. Never going there again. Sorry still a bit peeved.
