hi fellows i posted the question limp mode under my brother in laws id any way here it is i purchased a 95 cobra when i got the car it was wrecked but running i believe the car has had the engine rebuilt (due to chevy orange block and arp head bolts) ialso think the cam is aftermarket the egr was not connected so i just pulled it off i also in search of a little knock on the top end pulled off the intake got dissgusted with how small the factory tb is and replaced it with a 75mm tb i have an intake on the way so that it flow better. now the check engine light is on i had the codes checked and it pulled nine of those little buggars. I would like to know if there is some way to trick the pcm into thinking there is nothing wrong cause i really dont want to put hot exhausted gasses into the intake any info any one might have on this would be greatly appreciated. Also was curiuos as to wether or not it could be other sensors triggering these ones and if not where do i start. thanks again. here are the codes 327 came up twice 113 122 158 181 189 332 542 koeo engine off test. koer codes running test 314 311 327
