Well Guys I guess I didn't have enough yet with these 6.5 Diesel.Well anyways I bought this truck for 5,000.00 dollars it only has 68,300 miles. As You guessed it set ALOT....But it fired up sounds great. Put fresh fuel and treatment in.changed oil and moved the PMD.It runs ok at idle, but going down the highway and you step on the throttle it Surges and won't quit till you leave off and then it straightens out... Any Suggestions..Oh I changed fuel filter Also, I took the fuel out of where the filter goes and Dumbed Power Serivice in the filter housing. I'm in the proscess of doing it again tonight.. trying to clean the eye sensor out in fuel pump. I found out the Guy that had it dumbed Sea Foam in the tank. And from Experince with my other truck I found 6.5 Diesels don't like it...Well any feed back I will be VERY THANK FUL...
