So I started having this problem last fall, and the dealer cant seem to place it. Usually around 6k rpms, I get a CEL under WOT in cooler temps.

Also, when i get that CEL it usually falls on its face if I try to go past 6k rpms ( as if the fuel cut off has been activated ). I just recently changed the spark plugs, and I have no clue as to whats going on with the car. My mods are listed in my sig.

Im not running a crazy setup, and the car is still under warranty.

Any ideas??

 

Try putting the stage two pulley back on the stage two set up...the CAI along with the smaller pulley is probably making things a little hazy and weird.

 

dunno, kinda strange. My friend i\has a 2.8, same setup, no probs.

 

tried cleaning your maf?

 

no I havent. I also think I may have an older stage 2 flash. I had it installed in the beginning of 06. Ive got it scheduled to go in on Wed for a flash just in case.
