replaced tps, still running wrong
I was having issues with my truck , bouncing idle, bad throttle response, hard down shifts, engine braking, and really bad pulling while trying to maintain constant speed. sounded exactly like a bad tps. So I changed it out, cleaned the throttle body ports out . my truck is still doing the same crap, and the engine light turns on for a few seconds then turns off, every few days or so. I have odb1 system, every auto parts place has odb2 hooKup and cant read my codes.Is there a way to diy at home? and Would a bad fuel injector cause engine light to come on?
