Re: High idle

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

Re: High idle

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.
