97 psd rough idle poor throttle response Help!!
ive got a 97 f250 and i was going to church sunday mornin and i get to the end of my road and my truck starts idling extremely rough anywhere from 4 to 800rpms and i go to give it some throttle but it wont do anything till im 3/4 throttle. In the last yr ive put a new tps, cps sensors in it and I just put new d66 turbo, stage 2 injectors, clutch, and a tw chip on it along with new vavle cover gaskets and pigtails and such. It ran amazing the night before but now im stumped. and i need to get this resolved by the end of the week because i start college All help is much appreciated.
Im wondering if it isnt the icp sensor but im not sure. I ran the codes and all that showed up is p0603 and p0470
