P0153 Upstream Heated Oxygen Sensor circuit Slow Response - Bank No. 2
P0420 Catalyst System Efficiency below Limit - Bank No 1
P0430 Catalyst System Efficiency below Limit - Bank No 2
Car has an o/r x-pipe w/o MIL's so I expected this, but none of this helps me figure out why the car sounds like its missing and idling rough
I already replaced the alternator, coils, plugs and wires. I think I'm just going to replace the front O2's, get the MIL illiminators, replace the IAC, EGR, TPS and MAF... I don't have time to chase this stupid problem. If none of that fixes it then I'll check the timing, and if thats all good then I'll just replace the whole d@mn longblock.
