Running On 5 Cylinders During Startup (occasionally)

[Galois]

fantastic description kjb r33, thanks, i had wondered how it worked on an atomic level and you confirmed a few thoughts id had. cheers

Haha I didn't know you were running on 5?

literally half the time mate, and it's my daily . has been raping my fuel economy haha. ecstatic about getting new coil packs! imagine driving without fear!!

The coil would start working with temp as heat makes things expand, a broken internal wire for instance doesnt touch cold, get some heat in and now it contacts.

my conditions are similar, the car doesn't misfire once warm, and i dont mean oil is warm, i mean really warm. I feel it is the coilpacks, they probably take some time longer than the engine to reach equilibrium temperature. If I leave the car for 8 hours after a drive it'll missfire, and does every day on the way to uni (30 mins). but if i drive for say an hour it figures itself out.

It also only starts to misfire when i back off throttle, or at idle. and once it starts, the tcs, slip and engine lights turn on and the misfiring continues for several minutes at least, before eventually recovering.

It's a game I won't miss playing... just hope I haven't done any damage, it's been like this for months :|

lol atleast yours is misfiring, mine plain wasn't firing...nothing like the rich smell of fuel coming out of exhaust pipe and the shaking of the car

[Galois]

ahhhh, ok, so misfiring isn't a generic term for firing problems...

yeah mine was doing that, it's the worst feeling in the world, and a bit embarassing, though most people think that sound is intentional.

Sucks being down to like 40% power

My car sounds like a boxer engine when it's on 5 cyls, it's awful! People look at me like I've done an FJ conversion

[Galois]

hahaha i know the feeling!!! you see someone else in a done up skyline and feel judged! couldnt get on to performance wise today, not for lack of trying, will try again tomorrow

My replacement YJ arrived today

Thanks Paul!

If you're just wanting to order, Galois, you can order them from eBay as PW are on there with listings up.

[Galois]

ordered ordered ordered ordered ordered... excited lol

have you put the new coil in?

[Birds]

Yep, IT'S ALIVE! Starts on 6 cylinders everytime. Turbo seems to spool faster too, perhaps the faulty coil was performing poorly even when it was firing 6 cylinders.

[Galois]

Fantastic mate, glad to hear it! Will Performance Wise let you know what the problem was? It'd be interesting to know.

[Birds]

Dunno, I didn't ask. They probably will examine it though. I don't really care as long as my car is running

Probably a loose connection inside, manufacturing fault maybe? I doubt I would have burnt it out without damaging the others. Let us know how your coils go.

kjb_r33 i just quoted your explanation in the spark plugs thread, thought it should be in there...

no sweat

omfg the new coilpacks make it so rev happy! I have disconnected the stock boost controller to bring it back to a safe 7psi, good for the slipping clutch and was good for the misfire. Reconnected it and man, rev happy + 13-14 psi was insane!!!!!!

You were right when you said they make a massive difference mate!

Now to get the clutch done. I want to connect the stock boost controller to a switch in the cabin (however the hell i do that), was thinking along the lines of one of those missile fire switches in jets mounted on the gearstick, subtly somehow hahaha. For now I have a switch and wire and need to find a hole in the firewall

Good to hear buddy

It's something everyone should replace.
