Since I re-calibrated the TPS car seems to start easier and have more response , especially from idle.
From aftermarket manual the procedure is:
Install a 0.7mm feeler gauge between lower throttle stop screw and throttle stop lever, which are located on underside of throttle body. Do not use screw on top of throttle body.
Connect ohmmeter between TPS terminals 1 and 2 and check continuity is displayed.(these are the 2 top terminals after harness plug is removed)
Remove 0.7mm feeler and replace with 0.9mm feeler guage between throttle stop screw and the throttle stop lever .Check there is no continuity between terminals 1 and 2. If necessary , rotate TPS until adjustment is correct.
Tighten TPS adjustment screws and confirm the adjustment is correct.
Note: if correct adjustment cannot be obtained, renew the TPS.
Hope this helps
