I have a 2000 XJ sport 4.5" lift. I am running stock manifold/converters, with a flowmaster super 40 out back, stage 1 jet chip, poweraid throttle body spacer, rusty's airtube/kn filter, E3 plugs, and a painless hi-velocity 62mm throttle body. I have recently done a tune up and changed out the Idle air control valve, and TPS. After I put the new TPS in, the engine idles very high and my CEL came on. Put the old sensor back in and it runs ok CEL gone. Why would a new sensor cause this problem? Also the reason for the tune up is that recently i feel as though i have lost some HP. I have never changed the injectors, they have 150,000 miles on them. Should they be changed? and should i worry about my TPS ? what to do.... i don't know.... :banghead:
