Hmm...I've never had to do that before and am not even sure if there is an adjustment.Originally posted by cherokee:
anyone tell me how to adjust the idle
speed on a '98 -4.0L?
running about 200 rpm slow.
tried big hammer,no luck!
My two guesses: crank shaft position sensor (CPS) or throttle position sensor (TPS). If you recently got the engine really wet (like if you cleaned the motor), odds are the TPS is toast.Originally posted by cherokee:
drives/shifts ok,just an annoying rock at idle.(i'll tell everyone it's just a lumpy camshaft)
Check your diagnostic codes to see if anything comes up. Search for "diagnostic" in the YJ FAQ: http://www.bc4x4.com/faqs/yj.cfmOriginally posted by SaudiArabianYJ:
Same thing here but for a 2.5L.....I looked for a screw to adjust it and found nothing.
