I have an 04 Lb7..and it has a rolling idle by about 50 rpm.. And while driving the truck has a surge.. I changed fuel filter. No difference.. Truck has loads of power. The only problem it has is this surging. Any ideas..

My 02 does the same thing but only in idle. Once on the gas it goes away. Is this the same thing that yours is doing? I would like to get it fixed.

If I had a nickle every time someone asked about rolling idle, id have like ....a quarter.......yep...5 times....

Dump in a bottle of two stroke oil next time you fill up (its cheap), bet your rolling idle goes away.

This is going to sound like a dumb question, but what does the 2-cycle oil do to prevent this problem?

what exactly are we lubricating by putting the two stroke oil in the tank?

your lubricating everything in the motor, and everything that has to do with fuel...the ULSD sucks with lubrication and 2 stroke motor helps and i hear it actually quiets motor down a little
