i have replaced the computer under passenger seat (corroded terminal) i have replaced the injectors, plugs,plug wires, fuel pump, and sensor on side of throttle body. truck has sat for 1-1/2 years, it had 1/4 tank of gas in it during this period. after i replaced everything and got it running, it was smoking kinda bad i put in fresh gas and lucas treatment, it no longer smokes bad. truck will crank and run as long as i play with the accelerator. but once i let off the gas, rpms jump from 300 to 1400 about 4 times, then it dies. please help, thanks!
