If you didn't set the new tps with feeler gauges and an ohmmeter, you didn't do it right, and it needs to be done again. It is critical that this is adjusted right. Why was it changed in the first place?

The afm and tps work together to tell the computer how much air is entering the motor, and how much throttle is being applied. The O2 tells the ecu how rich or lean the motor is running and the ecu increases or decreases fuel. These are the 3 most important sensors your motor has, and each must be functioning correctly to run right.

 

Well hell man if you just add the ECT to that you have the whole EFI sensor system

 

Check your spark plugs gap and clean them too
