STERLING STINGER Posted August 17, 2012 Share Posted August 17, 2012 ive recently been noticing a rough idle in my 92. it will idle perfect for a couple mins, but then it seems like it wants to stall out...it will either stall or almost stall on me. It seems to do this even when i am in higher rpms on the roads....it sort of "bucks" also, its shifting all crazy...itll downshift or won't upshift when its supposed to. ive changed the map, plugs, wires, distributor cap n rotor, adjusted the tranny kickdown no clue what else to try. I'm going to change the fuel filter today and check the ground behind the drivers side tail light. hers the vid,,,its only doing it a little here ...it does it way worse than this Any help or comments will be appreciated.

HOrnbrod Posted August 19, 2012 Share Posted August 19, 2012 It's a 92 - check for fault codes. Link to comment Share on other sites More sharing options...
Geonovast Posted August 19, 2012 Share Posted August 19, 2012 Had an 88 XJ that acted similar. TPS was out of whack. Link to comment Share on other sites More sharing options...

mountainman Posted August 19, 2012 Share Posted August 19, 2012 Possible CPS going out. See what fault codes you have. I have damn near this same idle on my 91, and there are times i go to take off and it just loses all spark for a millisecond then kicks back in. SO short a duration. My rear main is going and i think there is oil all over everything in the bell housing. Didnt do it when i got it, now that rear main is pissin... its doing it a lot. I'm gonna be doing rear main soon and cleaning everything real good. Ill then report if my hunty idle and skipping running goes away. cool you posted this cause makes me feel better. Mine is doing EXACT same thing. that idle with pieces missing... lol. Link to comment Share on other sites More sharing options...

mountainman Posted August 20, 2012 Share Posted August 20, 2012 :eek: NICE! so now that helps my brain. if mine keeps it up after rear main and clean CPS, I'm gonna clean my throttle body and then maybe ill need a TPS too.
