03 TJ New TPS because of code p0122 now Code of p0123? What the heck All i did was put a new sensor in. it never ran like this before until i changed the sensor. my buddy scanned it originally and we got the p0122 code so went to checker and bought a tps, changed it and immediatley started running like crap and light back on. Any Thoughts. I have read alot of forums on this but they were old so hoping there is some new info!
