Good evening,

Why did you replace the sensor?

What is the code that is set?

What kind of noise is the shifter making? Can you upload a video of the noise for me?

Okay, the first thing I would do is check the fuel pressure to be sure the pump is supplying enough fuel when cold.

Pull off the wires to the IAC and see if the idle is normal. What valve was clogged?
