I have looked up many threads on cel P1391 but I can't find how to troubleshoot and diagnose what the actual problem is. I was driving home from work on i5 from Tacoma to federal way and going through fife the jeep stuttered and the rpms would spike way up under middle throttle then as I was getting to federal way it got worse and worse so I pulled Over and it stuttered even at idle and it died and through a code. I have a Bluetooth code reader in the jeep and it said it was P1391. Any thoughts as to where to start? I don't want to just throw money at replacing things that aren't the problem
