akirby Posted June 26, 2018 Report Share Posted June 26, 2018 Engine dies but usually restarts. Hesitation. May or may not set the CEL and a code. 2 Quote Link to comment Share on other sites More sharing options...
omar302 Posted June 27, 2018 Report Share Posted June 27, 2018 I believe one the things that made it hard to diagnose failing Throttle bodies was the fact that after a restart the diagnostic code in the PCM would be erased making it difficult for a dealer to confirm it. One more thing to add to the akirby's list, the vehicle would usually go in to limp mode and reduced engine power with a wrench symbol warning in the instrument cluster. 1 Quote Link to comment Share on other sites More sharing options...

Sometimes they do that but sometimes they just shut off completely. I think there are multiple failure scenarios at work here. 1 Quote Link to comment Share on other sites More sharing options...
