If anyone can help I have a Mack 95 model with a ea7 454 motor , I accidentally reset the idle low from what info I can find on the truck by playing with the cruise control switch , switched one to many times problem is I can’t don’t any info on resetting the idle back up as it has dropped to about 450 rpm bit to low and shacks for my liking any help would be appreciated cheers Gav
