I'm not sure yet, I have several codes on the car that keep pointing back to the ECU as the main problem. I know the truck runs pretty good except for the O2 sensors (which is due to it not having a muffler, catalytic converter or exhaust pipes-all removed when it was stolen for a month) and possibly the battery or alternator (I'm betting on battery).
