I have an issue w this ..2000 5.7 Vortec ..I set the CMP to ‘0’ ..cleared the code ..and it runs good ..but the idle will be fine ..and then flutter a little bit ..then fine again ..and when I shut it off and restart ..it sets the code again ..I’m wondering about the “relearn” procedure ..kind of lost on this one ..

Will it make your truck run bad and sound like raggedy like something broke.

Sometimes, they run badly, and sometimes, the engine won't even start. It can vary and depend how far off it is with timing information.
