Okay, started out as would not idle also threw a p0202 code. Fixed the injector wiring and installed new injector. Got a new battery. Now it somewhat idles at 1000 rpm. Took it to get re-scanned . Now it throws me two codes 1. P0202 and now a P1155 code. I think the injector is stuck open because I smell gas now when I am driving but checked under good. No leaks. When I turn off it is smoking out of tail pipe so the injector circuit must still be stuck and dumping fuel into the cylinder giving me the gas smell and the smoke put of the tail end. Also need help with the p1155 limp mode code. Please help!

see picture for cause for p202 may be a bad PCM or a wiring problem yet p1155 is throttle position actuator stuck closed. but code has been changed /modified from manufacturer. try cleaning throttle plate on both sides and IAC hole with choke cleaner that may straighten it out. it also may be the the throttle pedal giving this code.

The P1155 is the air mixture heater circuit failure, just replace the sensor. Here is a guide that will help you
