Hello fellow Saturn owners. I have a 2002 Saturn l200 with the 2.2, automatic. I had a miss in the engine, so i changed the spark plugs, the boots were only a year or two old, and atill looked very nice, so i reused them. I did get a new coil pack and ignition control module. I replaced all of this and the car wouldnt crank, it will turn over. My stepdad gave it gas before trying to crank it, and it crunk, but now it has a fast idle of nothing less than 4k. We have checked plug ins, wires for corrosion or breaks, and have found nothing. We check for vacuum leak, and found nothing. His computer told us the trottle body sensor was too high, so i replaced it. Nothing seems to be helping.

i should note that i also went theought AC system, replacing the compressor, dryer, expansion valve, and flushed the lines

Any help or ideas would be grateful.
