94 Chevy S10 Truck 2.2L - Loses performance when accelerating on inclines. Replaced plugs and wires...catalytic converter, fuel filter, MAP, MAP, temperature, O2, TPS sensors....seems to run better with TPS disconnected...but still has deceleration on incline. Take off and 1st, 2nd, 3rd gear good...but after that not good. Anyone have any ideas?
