High idle
My jeep is an 05 wk 3.7 and yesterday i noticed it idling high when i first strted it. Normally it idles at 900-1000rpms but when its in park or neutral it idles at 2k. Anyone ever have this problem or know what it is?

Re: High idle
When I first start it and it's cold out it can go as high as 1500 rpms

No it happens when it is warm, and the check engine light came on today. I have to bring it somewhere to see what code comes up.

Re: High idle
Pull the codes yourself using the key dance… start in the ignition off position then turn to the on position without starting the engine, off, on, off, on then look at your EVIC and it will display the CEL codes.

Re: High idle
You have to do the on/off part fairly fast but it does work.

Re: High idle
Tried again, even did it the same time and speed as video. Is that just for certain years?

Re: High idle
Pretty sure it works for multiple years since I've used on my previous vehicles from a '85 Laser XE, '95 Dakota, '98 Cherokee, '02 Grand & '08 Grand.
