I Noticed that my jeep started to idle rough so I checked for codes with the key trick and I got 06-02. I searched and found what it figured it was,
P0602 (M) ECM Fueling Calibration Error ECM Internal fault condition detected.
I also searched for info on this and couldn't find much but an explanation of the problem( not solving it) or an argument. Could this be my problem and what am I looking at? If there's already something out there for this a link would be awesome. Thanks
