    yes, im guessing you didn't adjust it properly...or at all. get a multimeter and tune it in. it will run much better and eliminate the high idle.

    try searching ADJUSTING the TPS

    Check out the Air idle servo. The tps shouldn't need any adjusting. Had the same problem with my old 97 tj 2.5 . Might just need to give the throttle body and air idle servo a cleaning.

    at first I thought I installed it improperly because it doesnt line up exactly had to sort of turn it to line it up with the throttle and turn it back....thats what I did first then I tried it by turning back the throttle so it looked to wide open to me then it fired up at like crazy rpm so I dont know. so its still idling high but the wife dont mind atleast she has easy take off since she dont drive stick really. but I'm sure its crushing the gas.

    I'm positive your problem is you haven't adjusted it. I adjusted mine after I installed it. Took me less than five minuets to do. Get a multimeter. At the price of gas it's in your best interest.
