Yah so I thought I would share this with you. My 99 XJ 4.0 started idling way high the other day so I replaced the TPS, IAC, CPS, and MAP. Still had low/high idle, misfire, sputtering etc... Checked the fuel, spark everything on that damn thing.... Turned out to be the clock spring. Who would have thought that Jeep would be so smart and share a PCM ground with the clock spring and TPS causing the TPS to have high voltage and code P0121? So if you ever get that code unplug the airbag and the horn harness and it should fix it. Go figure.
Cant wait until my Audi is done so I can park the Jeep and not look at it for a while!
