2004.5 Idle Concern
I was just wondering what the normal idle is for my cummins as far as highway speeds. It sits at about 2 grand rpms which to me seems a little high at 70 mph but it could be normal. I thought it might be something with the gearing. The tranny doesnt slip a hair so I didnt really think it was my trans but thats why I figured id ask someone who knows more about this kind of thing?
Thank you.
Thank you.

Yeah these beasts make a bunch of torque in the lower RPM's. I never really rev mine past 2 grand. Usually thats just accelerating, but I almost always cruise at 1600 to 1800 rpms. Welcome to the Cummins family....

BTW, with a few easy basic mods like CAI or BHAF air filter and free-flowing exhaust, can wake it up a bit and also increase your fuel mileage. These trucks are quite fiel efficient to begin with.

Haha nice and thank you. Best part is im a die hard Chevy guy I live by their gas engines but I will not touch their diesel line. I think Cummins is better then a dmax any day. One other thing.... is it normal when you rev it for the rpms to not drop the second you get off the pedal? Usually it gradually comes back down on mine.
