Message:: [QUOTE="SpiritWolf, post: 3961545, member: 89863"]Further diagnostics.... So yesterday I had new fuel filters put on, and it didnt help. If anything the problem is getting worse. But at least I have a bit more detail on what is happening. Cold, she runs fine. about 30 or 40 minutes after hitting the highway, it becomes harder and harder to maintain speed. if I try to maintain 65, she will get to that speed, then suddenly rpm's drop to exactly 1000, and I am stuck coasting down to 30 or 40 mph. nothing I do to the accelerator pedal makes any differance. if I try to maintain 60, she will drop rpms to 1000, but usually gives me power back before I have coasted to 50mph.... if I try and maintain 55, she will do the same drop to 1000, but will 90% of the time recover power before I have lost more than 3 or 4 mph....  trying to hold speed with throttle or cruise control, the same thing happens. #1. It is Always a drop to 1000rpm. #2. the faster I was going when the power loss hits, the worse the loss of speed before I regain power. #3. Sometimes pumping the throttle will recover power, sometimes not. #4. Still no codes being thrown at all.. ::sigh:: time to hit the road to limp the last bit into Missoula from Butte. Going to head strait to the volvo dealer, and see what they can figure out.[/QUOTE]
