We have a '93 Club Wagon with a 5 liter V8, and it died the other day. We replaced the coil, cap, and rotor, which got it running again. Now the engine idles way way too high. We thouroughly cleaned the IAC and replaced the TPS, and it still idles high. We didn't touch anything else in the area where we were originally working. If I take my foot off the brake pedal and don't touch the gas, the van will easily hit 35-40 mph on its own, and its not safe to drive. Any ideas would be much appreciated.

Thanks
