Pulled codes, help me pinpoint problem (KA24) - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Hey there Zilvia, I'm hoping everyone out there can help.

I'm pulling codes 12, 21, 32 and 34 which in order are the maf, igntion signal, egr, and knock.

The engine runs rough at idle, almost as if it's cammed, unplugging the MAF causes it to go into limp mode and it runs exactly as it should in limp.

I've tested the MAF and I'm 100% sure it's functional.

According to KA24Developement.com code 32, egr is only for cali models.

I bet the knock sensor code is due to other problems since the car does have pretty bad inconsistent misfire.

Any ideas? Is something perhaps not plugged in that I'm totally missing?

Matt

timing could be a little off, check your dizzy and rotor, fuck egr and wait till its all fixed to address knock.
