High Idle Problem Fixed
It was my ECM that was bad. The scantool was saying that there was no tps voltage and the wires to the sensor were good. I tested the TPS by removing it and putting on a new one. That still didn't fix the problem. I replaced my ECM and That fixed the Problem

Re: High Idle Problem Fixed
It still runs a little rough, but I was getting around 13-15 mpg in the city when it was idling high.
