Review on 🔧 Enhance Engine Performance with GM Genuine Parts 12670981 Fuel Injection Throttle Body Assembly and Sensor by Jason Hinrichs

Fixed RPM unstable. RPMs jumped at cruising speed and when climbing hills. I never had any money on the check like others or Stabiltrak. Rough speed only. Easy installation. Bring the head to 8 and loosen the clamps on the breather pipe. Pick up the handset. Disconnect the sensor wire from the throttle position sensor on the throttle body. Unscrew the four 10mm screws on the throttle body and remove the block. Clean any oil residue in and around the intake port and screw the new throttle body onto the intake port. Connect the sensor cable. Install the breather pipe and tighten all screws. I didn't have to replace the throttle body gasket as it appeared to be in good condition, but you may need to. I didn't have to go through an idle retraining process either.
