Missfiring Fixed, Now Somthing Else...

[MUZT3K]

Ok, my car was missfiring with splitfires in it, so bought some new spark plugs gaped it to 0.8mm put it all together started it up...now its idling like shit, really rough sound, kinda sounds like it wants to stall but the revs arnt jumping...i also can hear a air leak in the engine bay. any ideas guys?

I had the same problem when changing plugs. Didnt take the crossover pipe off just shoved it aside and it made a hose pop off. Look near your bov and you should see 2 hoses going underneath, one of them on mine came off and it idled like shit.

You changed the plugs, now it idles shit and you can hear an air leak? I think you just nailed it.

Unless the air leak sound is coming from the PCV valve or hose connected to it. It always sounds like rushing air when the engine is idling.

i forgot to mention this air leak i speak of was happenin before i put the spark plugs in, but now the air leak sounds louder... heres a picture of where the air leak sounds like its coming from but i cant tell which hose it could be.

That is the PCV valve hose. That is a normal sound

could be the intake manifold. my old r33 had a leak in the intake manifold, you will know it is there if it doesn't idle smooth; this is because it runs lean and the computer forces more fuel causing it to run rich. if you can smell it running rich i would say its the intake manifold.

its not something silly like the coil packs pluged in ass about??

Check that you plugged the igniter plugs back together properly (at the back of the motor on top of the coilpack cover... Mine's a S1 and I last time I removed the igniter and didn't put everything back together properly it sounded like a WRX and was idling really rough and all over the place.

I thought it was plugged in but you have to push it hard til you hear a click. Dunno if this is your problem but it's a simple one so you might as well check hahaha

Use your hand and feel around for the air leaking, nothing in that area bites.

Just keep your hand away from the shit at the front of the motor (Like fan, alternator etc) and you'll be sweet.

It's how I find my air leaks, listen, then feel.
