dirty maf wires, bad iac, those two working together with an idle that is too low or causing a low idle

I had stalling going from P to R. Ended up being a bad MAF.

To test the TPS pierce the green and black wires (i think). Preferred setting is .98-.99v. Use a digital voltmeter.

The stock TPS can be made adjustable by enlarging the holes a little. Do that, rotate the TPS while checking the voltage. Once its reading good tighten it down but dont overdo it, the TPS will crack eventually.

Even ifa stockTPS reads ok, its always nice to have it adjustable. The IAC is that silver thing on the side of the throttle body. Careful with the gasket if its never been off, sometimes they stick.
