I was messign around with my Hypertech Power Tuner when i first got it modding my jeeps system and after i programmed it i got that code, now i know what it means it pretty much means teh ECU is crapping out on you. right afterwards i returned it compeltly back to stock but the CEL wouldnt go off even after clearing it. my question is, if i need a new ECU what years can i get it out of? or what cani do to try and fix this i have undoen the battery and even unplugged the ECU for 20 minutes with no luck!!!
