Bad Coils

[smurf80]

hey guys,

I'm just wondering who with r34s on here have experienced bad coils? I've searched around and found problems with a missfire in the 4000 to 4500rpm on turbo cars but what do NA symptoms have? how can u tell its a coil and not a plug without physically inspecting it? reason I ask is mine is running like a dog (sounds like a WRX) and there is a lot of stuff to unplug to get to the cam valley to check.

so any help on what the symptoms are would be great I suspect its a coil but need some reassurance.

thanks

NA's with bad coils experience the same problems as their turbo counterparts. My last car was a ca18de and i went through about 12 coils on it. Car feels like it's missing a cylinder and sounds like a wrx but without any pull. There's a few threads on coil maintenance and cleaning, check them out.

Thanks again for you help howie, much appreciated.

Also can anyone tell me it is a coil from my symptoms?

Cold start is fine will drive around OK for a long time or short time its totally random. Engine light comes on car sounds like a WRX has poor accelertation etc. But when it is driving OK it does have a miss as well?

Any help would be great

Cheers

Generally speaking, nissan coils generally get worse when they're hot. On my previous car, when the coils were bad they would generally be okay for about 30 minutes then it would sputter and the engine light would flicker as you say.

How many kms has your car done? has it ever had the coils replaced? I would definately give it a good clean, take out the carbon deposits on the tip perhaps give it a light sanding, silicone the boots and clean the leads. Come back and tell us if that helps solves your problem.

Investigate the possibility of going to splitfire replacement coils... I wish I had known about them earlier, that would've saved me going through a dozen coil packs.

Thanks again Howie will give that ago. Car has done 60,000k's Can they go around there? I have heard R34's are notorious for coil failure.

My first set went at 68,000kms on my last car.

It's not just R34 notorious for coil failure, it's basically any nissan car pre-2001 that uses the coil pack system. CA/SR/RB's.

My R34 N/A had the coils die, wasn't until I put the turbo on the problem was more noticeable.

ive had my r34 for 7 months and had 3 coils go on me. in the end i replaced all of them with splitfires. its too costly too continue to replace each coil as they go. my r34 n/a has done 67,000. the last 2 times i lost the coils the car would be running on all 6 cyclinders, then lose a cylinder then gain it back etc. those two coils where showing a greater heat resistance to the others. hope this helps!

Yeah replace them with splitfires..I bought my car with low k's and it was the first thing I did as I never wanted to experience the pain of running randomly on 5 cylinders ever again!!!

yeah. they arnt that great. it seems the newer the car the worse it is (except ca18 lol)

[sh@un]

why does it seem 32/33 GT-R coils are better than RB25 or 34 GT-R coils?

[Trust33]

What other coils (stock but other cars) are there out there that allow more spark and relativily easy install into our skylines?

[Trust33]

I have found a post from here on sau but it diddnt have any pick.Though there was a link.it has pics and is a tutorial.

Thanks guys for the info. It will be all fixed this week (hopefully)
