I've gto a 92 jimmy 4x4 with a 4.3 CPI and it's throwing out a code 43. The engine also has hardly any power. From time to time it will surge with tons of power but mostly not. What do you guys think it is?

Well code 43 would be your problem. Your TPS needs to be adjusted... Code 43: Throttle Position Sensor (TPS) out of adjustment
