6.5 turbo diesel

2000 3500HD with low mileage (75000 Orig) When I am going downhill or on a flat surface the engine surges often dropping as much as 800 rpm. If I move the accelerator pedal slightly it snaps back. I also cannot press the accelerator while sitting still and maintain a constant rpm. It wants to...

Hi folks, I’m looking for a few good gurus to help me with my project. I have an ‘89 GM diesel crew cab. She spent many years as a fleet vehicle for a pipeline service company, then went through half a dozen private owners before I rescued her. I was told she had an 6.2L originally, and that...

It’s hard to start with one particular spot on what’s wrong with my truck. I have a 97 chevy c2500 with the 6.5 turbo diesel. I had a p1214 code and I used a tech 2 to find out I was at 2.46 degrees which should be .25-75 after 77c or 170 f. I ordered the 3 wrenches to adjust the pump. Adjusted...

Hi Everyone, First post here, but been browsing the forums for the past two years. Grateful for the wealth of information archived here. I purchased the truck in my sig in the spring of 2016, and it came with an extra tune. I was told by the owner that the truck currently has a "buddy" chip in...
