[QUOTE="Gatorbrown, post: 443267, member: 21159"] I should tell all a little about my Jeep. Rory is a 2008 Jeep JK, 2 door manual transmission equipped with a nice Sprintex super charger. I keep getting a P0171 code and it smells a little like exhaust in the cab. I cleaned my mass air flow, cleaned air filter, and replaced upstream bank 1 O2 sensor. Also checked all hoses and connectors and saw no obvious vacuum leaks. Still getting the P0171 error and noticed that catalytic converter seems to be making noise near the O2 sensor I replaced. Makes me think there are issues with that cat but of course I would rather not replace right away. Has anyone tried cataclean with their JK? I figured it was worth a try because Rory is really running pretty strong except for P0171 code. Thanks all for any pointers offered. [/QUOTE]
