I feel like ive had close to this problem before with a bad coil pack, but no stalling this time. Idles fine, on acceleration bogs/skips/struggles, its not to the point where I cant drive it but something is definitely off even in the upper rpms (3.5k+) you can hear that its a little off. Im thinking leaky fuel line because I smell some gas, but nothings leaking, so maybe some leaky injectors? I replaced the spark plugs thinking they were fouled from running a little rich.
N/A 91 btw.
Suggestions?

 

Ohm test your injectors, they should be between 10-14 ohms. Also try cleaning your connectors to get rid of corrosion.

 

Yeah, I cleaned the connections, they weren't too bad, I need to wait until tomorrow to test em, will this tell me if they are leaky though?

 

Nope, but they'll tell you if any of them need to be replaced. I've heard injectors are a very common problem with z32's.

 

Hmm well if this is looking like the definite problem maybe ill just buy some new ones, I heard they are decently cheap.

 

Are you sure ALL of your coilpacks are working? beats me, could be injectors leaking.

 

If its a coil pack again im going to be pissed, I suppose I could check that as well tomorrow while im under the hood, although I dont think it would be idling/starting flawlessly with a bad coil pack. Its only on acceleration

 

Could be CAS, only giving out enough power to the injectors at idle, and on acceleration it may not be supplying it good enough.

 

your shit's fucked

 

Thnx Dimitri, Yeah, im also going to check the timing tomorrow, I just dont have a wire to put from the spark plug to the coil pack...but if the problem is just the timing, it would make me very happy.
