Throttle position sensor

Have 98 wrangler and have replaced throttle position sensor several times. Just installed new one, cleared the code and immediately got new 0122 code. Any one have similiar experience ? Car sometimes misses, bucks and acts like fuel problem ????

Sounds like corrupted wiring or referrence voltage problem. May need a scanner or dvom to see whta the actual output of your tps is doing.Get a wiring schematic and study the TPS curcuit to bertter understand it.
