4.3 with 197,000 km. I had the tranny rebuilt in Dec. Had code 0300-multiple misfire. Replaced plugs, cap and rotor O2 sensor, catalytic converter. Fuel filter replaced as well. Truck runs fine on flat ground and small hills. No more engine codes, but.
Drive up a steep incline, truck will lose power than sputter, and chug hard. Wants to stall. If I leave it at an idle for a few minutes, idle will return to normal, but can't get it up the hill.
What's going on?
have the same problem?
