So I installed my high idle switch this after noon and I'm have issue with the temp gauge shooting up to +200 in 6cyl settings. I tried shutting the truck down then switching settings. Then starting it back and the issue goes away in the mpg setting and 3cyl settings.  I tried the 6cyl setting again and same issue. I uninstalled the unit now it goes into 3cyl high idle with out the unit being installed. I have it set to the off position now and it idles normal now. Any ideas on trouble shooting the issue. I followed all the install instructions and check the wiring for any pinched wires or connecters not being plugged in all the way and everything checked out. 

 

Email support@mopar1973man.com  and we will get a new switch out to you.  

 

I have been looking at the recent issues that have come up and it appears that the batch of rotary switches are causing issues.  I have since adjusted my testing to ensure that the rotary switch is in good shape.

@Me78569 how recent was this batch made, I got my switch maybe within last year but yet to activate ECM. Is there a way to know which switch I have by looking at it.

within ~2 months.
