I am having issues with the truck dying at idle with a/c comp on and in gear. Is the truck not getting enough fuel? New filter, #5 fuel plate. No other mods than listed below on sig. 98' 2500. Has anyone ever had similar issues? what was done to fix?

 

What RPM does it idle at with AC on in gear?

Below 750-800 and you need to turn it up.

 

Is there a proceedure to turning it up? It idles at 600 normally, and drops to 500 in gear and with a/c on.

 

Your idle is too low.

thank you, I will add it to my list of fixes for this weekend.
