Because of binding at the accelerator bushing, I obtained a
throttle body for my 1989 S-10 Chevrolet pick-up with a 4.3 liter
The engine, with the new throttle body installed will not idle down.
The old throttle body worked ok with proper idle and the computer had
been replaced previously with a new one because the old one failed. I
went with the re-manufactured one because the binding of the old one
caused the accellerator to suddenly give and you would suddenly speed
the vehicle forward. In other words, there was not a smooth travel of
the accelerator and when you pushed on it with your foot, you had to
press hard and then it would suddenly give with more speed than you
Does anyone have any ideas? I understand that there are adjustments on
the throttle body itself. I disconnected the battery overnight
thinking the computer might need to reset itself but there was no
effective change. I hope that I have made myself clear.
