JeepinDude Posted September 21, 2015 Posted September 21, 2015 I was doing the C101 connector refreshing on Cruiser's Renix Tips and while I was at it I cleaned the TPS and the IAC (just the connections). Well now I have a high idle problem. It revs up to about 2000 rpms right when you crank it and does not rev down at all.
88whitemanche Posted September 21, 2015 Posted September 21, 2015 What did you use to clean the tps? I once let some gas fall on the tps and it killed it the next day... You may have to readjust your tps as per cruisers tips and go from there...
reubj Posted September 21, 2015 Posted September 21, 2015 Check the ground connections at the dipstick. A loose connection caused the exact same thing to occur on my Renix.
ParadiseMJ Posted September 21, 2015 Posted September 21, 2015 ...and check to see if you dislodged/cracked or disconnected any vacuum lines on the drivers side of the engine.

You may have to readjust your tps as per cruisers tips and go from there... I use some spray electronics cleaner.I don't know if it could cause this but I may not have let the cleaner evaporate fully and there my have been some sitting in the connector on the TPS. I'll adjust my TPS while I'm at it. I'm sure it won't hurt.
JeepinDude Posted September 21, 2015 Author Posted September 21, 2015 Check the ground connections at the dipstick. A loose connection caused the exact same thing to occur on my Renix.I'm actually gonna do that today after work. I looked at it last night and it need cleaning
JeepinDude Posted September 21, 2015 Author Posted September 21, 2015 ...and check to see if you dislodged/cracked or disconnected any vacuum lines on the drivers side of the engine.Could a vacuum line cause it to idle that high?
JeepinDude Posted September 21, 2015 Author Posted September 21, 2015 I'll check them then. Probably could have snagged one by accident. I just didn't think that it could make it idle THAT high. I know that one will change the idle speed slightly if disconnected but I'll still check
ParadiseMJ Posted September 21, 2015 Posted September 21, 2015 The bigger vac lines...like the brake booster to manifold and the "other side of the engine" HVAC and Cruise SOURCE line coming off the manifold would definitely make the idle high. Smaller lines maybe less so, but a good time to check them all out. The smaller lines on the passenger side would show themselves by the HVAC, heater valve and cruise not working quite right.
JeepinDude Posted September 21, 2015 Author Posted September 21, 2015 Ok, its definitely gotta be the TPS. When I got home I checked the vacuum lines and didn't see anything wrong so I cranked it up to see what would happen after sitting all night and most of the day. It ran just fine if not better (might just be in my head) until I tapped the throttle once then it revved up back to 1800 rpm and stayed there. Well i unhooked the TPS and it revved back down. Hooked it back, stayed fine, hit the throttle, revved back up again so its gotta be the TPS and all i need to do is adjust it right?
reubj Posted September 22, 2015 Posted September 22, 2015 Make sure the TPS has a good ground. That's exactly ho mine would act.
JeepinDude Posted September 26, 2015 Author Posted September 26, 2015 Ok, sorry for the late reply but the problem is fixed (so I hope). I cleaned the ground connection at the dipstick really good and i also noticed the nut holding the grounds on the stud wasn't tight at all. I've been driving it and so far no more high idle Thanks everyone for the help... I've learned some new stuff from this
