Hey all, I have a problem where it seems like the truck is pulling a 20,000lb trailer and it has absolutely no power. Basically an almost full overhaul: Recently rebuilt Motor & tranny. Idles great about 1,000rpm soon as you put it in gear it bogs right down to about 500rpm and barely can move out of its own way. New Ignition Coil, Module, Plugs, Distributor, Rotor, Cap, VSS, Crank Position Sensor, IAC, TPS, MAP, MAF, PCM And the only code it is throwing is the P0108 - Manifold Absolute Pressure (MAP) Sensor Circuit High Voltage I'm not really sure how to read this, is this an overlimit on the value it is expecting because of the sensor working as intended or is this an electrical issue where it is receiving to much voltage? And would it explain the engine lacking power? Just at a loss as the codes dont seem to be telling me much, and just can't seem to get power out of this motor.
