Gav Posted November 4, 2021 Share Posted November 4, 2021 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 Quote Link to comment Share on other sites More sharing options...
fjh Posted November 4, 2021 Share Posted November 4, 2021 (edited) Rev the engine with the foot pedal or cruise control to the desired set ie: 650 depress the clutch pedal ! I believe that will lock it in! https://f01.justanswer.com/diesel3153/b783e0a3-7099-4672-8fa2-def5c4dff508_Mack_engine_speed_control.pdf That there was posted by Mack pro awhile back!

Dirtymilkman Posted November 4, 2021 Share Posted November 4, 2021 Flip your cruise on/off switch to on the off three times fast. Then push on the accelerate switch to set your idle where you want it. Quote Link to comment Share on other sites More sharing options...
