hey havent been on here in a long time because i switched over to cummins motors. Well im glad i kept my account when i sold the chevy, because both my cummins are broke down right now and well guess what, the mighty old 6.5 has came to the rescue. 3 days ago i bought a 93 with a 5 speed, had to time it and do some clutch work on it but for 1800 bucks i couldnt pass it up. Anyway on to my question, when your drivin down the road it has a tendancy to want to lunge or lope so to speak when you let off the throttle, only way to get it so stop is push in the clutch or hit the throttle. I was wondering if this could be the timing chain (from what iv heard they have one). Also its like it dont have any power between 2500rpm-3000 sometimes and then its like the charger lights and it takes off and has some real good power for a 6.5. and sometimes when you mash the throttle its like it defuels until you let out of the throttle. I dont know much about them but im learning. thanks!
