I got my girl a 2001 s-10,4.3 vortec , 2 door. Replaced fuel pump, fuel regulator, thottle positin sensor, air idle control snsor , air filter and rotor button. It now cranks first time key turn, runs great going down the road.
When you start of it does not want to go from stop unless you take it slow untill about 15 miles an hour. It acts like an early model with the distributor timing set retarded. is there any sensor that could cause this without giving a code.
