I had some work done on my jeep but now it is idling faster--it runs good but I need to know how fast should it idle,I dont want to do any damage to my jeep! Thank you

 

i believe my 01 idles around 600-700

 

In park between 500-800. It will fluctuate a little here and there. Not sure about drive I have always had a manual cherokee... And thats also a renix.

 

Thanks so much--mine is idling between 700-800- to me that seems a little bit fast ,but --I dont know? just learning alot of this stuff..Love this site! Thanks again

 

Thank you,mine is 700-800 seem's a bit to fast!

 

Thank you

 

That's where my 98 is. On a cold start up it'll be around the 1200 ish but it'll work its way down to 750 ish

 

Could a dirty IAC cause it to idle around 1200rpms in park after driving for awhile? I've got a cracked exhaust manifold too, for now.

 

cracked exhaust will cause the increase in idle, had mine welded and it is holding strong after it warms up the metal expands and leaks more and increases idle

 

Mine is 1000-1,200 on start up to..
I guess mine is where it should be?!! Is 800 to hign? After warming up mine stays from 750-800..
Thanks --

 

Nah I think that's where mines at really

 

Thats good to know--mine always idled LOW -but run good that way!!-- after I had some work done on it the idle was faster-I have noticed that with the idle runing faster that the temp runs a little bit hotter(not hot) but the lower the better--so I am hopeing my idle will go back down on its own after i drive it awhile!??

 

My 98 XJ runs around 750 at idle.
