I'm doing some work on a '96 2500 4x4 with Cummins. Seems like everything I wanna do is mostly hidden by the vacuum brake system or hidden under the injection pump.
I tried to adjust my idle today. I got the 10mm jamnut on bottom loose, but never was able to adjust the idle bolt. I was thinking about taking loose the fenderwell inner liner to give better access. Is this a good idea?
The inner fenderwell liner has some kind of plastic fasteners attaching it in place -- almost looks like a rivet of some kind. It has a tiny circle in the middle of the fastener about as big as a pencil lead. ?? Do I have to drill these to remove them??
If this gives good access, I was thinking maybe needed to modify the inner liner to have some kind of easy access port. Anyone done this??
