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.

Replaced MAP sensor and TPS. Now wont even stay idling weather hot or cold. New code for IAC malfunction, but I replaced that 3 weeks ago and fixed itself for a bit.

Everything working now. Clogged air valve. But now when I start it it idles fine for 3 seconds then raises to 1,500/2,000 rpm's. I replaced IAC 3 weeks ago so it shouldn't be that. No engine light.

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