There are 3 wires on the TPS one is power in. One is signal out and the other is basically a ground. Need to figure out whichone is the signal wire. Attach a DVOM and check voltage on the signal wire. SLOWLY press the accel to the floor. The readings should go from approx .5 volt to approx 5 volt. IF the inital reading is a little higher say .8 thats ok. Make sure the throttle body is clean. Use a good 3m throttle body cleaner. Make sure that the idle air control motor is clean. Check the EGR Passages make sure they are open. Check the EGR itself. Make sure its not stuck open.
