Any ideas or anything just post em up here.

no ideas?

when you pulled the plugs were any (specifically #1) wet with gas? did you swap out the injectors or checked them for leakage?

Engine An occasional problem on this vehicle is the failure of the Exhaust Gas Recirculation (EGR) Valve passages. Failure of the EGR Valve passages can cause the Check Engine Light to illuminate, and cause the engine to run rough. The cost to clean the EGR passages is estimated at $25 for parts and $227.50 for labor. All prices are estimates based on $65 per flat rate hour and do not include diagnostic time or any applicable sales tax. Moderate Problems

Ill check out all the egr stuff tomorrow. Didnt even think about it.

Is there any way i can just throw a jdm intake on this biznatch and bypass the egr without a CEL??

good question. ya can on a b13, which is what i have, but your p11 may be a different story since it's obd2 with more electronic control, but you do have an old maf so may work just the same pulling the egr install the jdm intake, bypass egr, clear the codes and see what happens

check out g20.net, there is info on this and guys do it all the time

I know thats where im stuck

the only issue over on the g20 boards, is the fact that you have to contribute to see the how to's

AH no mula in the pp account.

another reason ill stick with my home forum

no kidding??? hmmmmmmmmmmmmm.....

i started out on sr20forum, i'm on here too, this one is better so far

sure there's gotta be some write ups on the same motor here, but deleting the egr is not hard. just take a bunch of stuff off and plug the exhaust hole and maybe one more.

maybe this will help:

Is your MAF working properly? Any leaks on the air intake system?

Im guessing this car got some water in the maf from the storms we had lately. Also, heard aftermarket oiled filters can get oil on the maf wire. How did you put the b13 maf in the p11? I tried to put a p10 maf in my friends p11 and the connecters were totally different.

90% of the time "its the maf"

A few times before I have had the furthest extension of my cold air intake pipe fall off so all air intake would begin right at the MAF. It caused my car to surge violently.

That is why blackwater and I say MAF. Despite the fact that you changed it to the original, is the original one clean? Get some MAF cleaner and clean the wires themselves and clean the connections as well.
