Start the car, it would run for a couple seconds and then dies out. Sometimes it just cranks and takes multiple tries to start it. Immobilizer light goes out when I put key in.
We replaced the fuel pump, fuel filter, the throttle position sensor where the cable goes into AND the other throttle position sensor that’s near the IAC motor. We pumped out all the gas and put in new gas along with some chevron fuel system cleaner. We cleaned the throttle body, the MAF, and it still does the same thing
Once in a while, it will start up and run for like 10 minutes and then it dies. This was a new thing after replacing the throttle position sensor near the IAC motor. If I start it and give it gas, it will stay running, let go of the gas and the RPMs fall and it bogs out or dies instantly.
Now a new thing popped up. Check engine code P1129. Press the gas pedal and it wouldnt respond but the car stayed running for a long time again. Then it died. Start it again and now the gas pedal responds but car died within seconds.
We checked the EFI relay and the 20a fuse near it. Both are good.
What should I look at next? Thanks!
