I have a 97' Cobra with a P1SC and 3-core intercooler running 10lb's of boost. I have FRPP 42lb injectors, Lightning 90mm MAF, SCT chip, Walbro 255 in-tank pump, Diablo Mafia, Anderson power pipe, Bassani X w/cats, magnaflow 2.5" cat back, 4:10's. I have been having a stalling problem ever since the second time I had it tuned after the blower install. When it is warmed up and I come to a stop it dies. It has been doing this for a while somedays worse than others. Then yesterday I got these CEL codes and the idle is erratic and it is stalling a lot more frequently now. The p1232 code is Fuel pump speed primary ckt fault and the p0122 is Throotle position sensor A ckt low input. I am pretty sure my TPS is bad, going to double check it tomorrow. But I need help with the other code, any suggestions? Do you think it is in the tune or something mechanical? My Lt trims are 25% at idle which could be part of the problem, but I am looking for some factual evidence before I have it retuned or change parts.
