Unbolt it and make sure all that mounting is clean and tight. Also as far as the throttle body when they set throttle position codes without unplugging it you usually end up replacing the throttle body the harness to it and a harness mount that keeps the new harness you splice in from vibrating and breaking the wires inside the insulation.

What causes throttle body pressure to go down?

Airflow Disruptions from Vacuum Leaks or Throttle Stop. Vacuum leaks can disrupt the air-fuel flow because of an imbalanced airflow, which can cause throttle body pressure problems. The issue could also be an incorrectly adjusted throttle stop.

Can a throttle position sensor stop a car from starting?

Similarly, can a throttle position sensor stop a car from starting? The only way a TPS will cause a no-start is if the TPS is busted/stuck, and the TPS is telling the computer that you’ve floored the gas.

While it is running you can plug it back in and will stay running but it still has almost no throttle response from pedal. Still diagnosing the problem but have already replaced throttle body and harness with no success.

Can a bad throttle body cause an engine to stall?

When that doesn’t happen, because the throttle body is dirty or faulty, the engine may stall. Problems with the throttle body can also cause an unstable idle. The PCM bases its idle calculations on a predetermined amount of airflow through the throttle body.

What should I do after replacing my throttle body?

After replacing the throttle body to your engine, if the engine light was on and has a pending code, the code will go away. If the code was a hard permanent code, then the ECM (computer) would need a hard reset. Remove the negative battery cable (-) and keep it off for about 13 minutes, then hook up the battery cable and make sure it is tight.
