Hey guys, my car is revin at like 2k at idle? sometimes it revs at like 1500. but there are no vacume lines unpluged or anything. any one have any ideas?? its a 91 crx dx. thanks alot

check the idle adjustment screw....thats all i can think about....lets start with that...

 

any codes?

my 88crx si was doing this 3 months ago. it turned out to be something wrong with my coolant system. Air bubbles were getting into the coolant lines and thats what was causing it to rev. hope this helps a little.

good luck

 

does this happen if u let it idle for a while....once mine warms up it usually goes back down to good old 750 RPMS

 

so iv been workin wit her for a while now, i had previously: blead the coolent system, there are no codes, but the prob no more is the idle at 2k. now it likes to fluctuate from 1000 - 1800 rpm. my teacher told me to check the timming on the cam, i was off a tooth actualy. so i turned it to the correct tooth. started it up, ran fine, my throttle cable was loose so my boy tightend it for me, just so there wasnt any slack, then it started flutating again. there are no codes, its drivin me crazy, i can drive it, but i cant take off, like i cant creep, it bucks, because it flutates, but i found if i unplug the Idle Air controle valve, then it doesnt flutuate any more, it just idles at 1100rpm. then after 3min. it starts doing it again. PLEASE HELP ME!!! i need to go home tomarow for the weekend from college home is 3hours away. any help would be great. IM me im on all the time!!!! CRXsiR84 is my AIM sn.
