hey everyone...i have got a problem with my jeep
I have had my 87 MJ for 3 years now and a problem has just recently in the past year or so has started. Sometimes after i start it the idle with go up to about 2000 rpm and won't come down and sometimes it will drop to normal and then pop back up. i have a new engine and have pulled the throttle body and cleaned it, replaced iac, tps, etc and can't get it to stop...although it sometimes will go days without doing it but then just gets a bug up its a$$ and does it every start up...now the strange thing is if i start the truck and its doing this i shut it off and push the throttle linkage at the TB under the hood then start it back up it idles normally?? I am completly lost and would appreciate any help....MJ RULE
