I did all of thee above i can start the car becuse the main fuel pump out side the car is working .i replaced the in tank fuel pump becuse it was shot tried to clean it and start it sevral times .anyway it did not fix my idle problem ive replaced all vaccum lines intake boot ,throttle switch,icv,temp sensor,fpr,every thing but the ecu nothing car does not seem to idle well unless i bump them up to 1,100 rpms this car is not stock alot of things done before i got it that may have somthing to do with it. one is that the exhast is high performance three inch all the way back to magnaflow muffler stainless steel dinan headers .but i dont think that should effect the idle ,the head had been done before i got it that might be it valves may need adjusted .who knows at this piont ive tried just about all i can .giving up and taking it to a shop.
