5.9L V8 Specific Topics
I've had the problem ever since I bought the truck back in August, and its just been getting slightly worse and worse as time goes on.
Truck is a 1998 5.9L 4x4 with just under 170,000 miles
Okay, so the problem: about 2-3 minutes after I start it, the RPM's will drop down to around 500 or so...
