I have already posted a thread about my f350 sputtering at speeds of 45-60 mph. If i let off it stops or if i keep it above 2000 rpms it wont do it. I have had it put on the copmuter and no codes! I know my clutch fan sensor is bad and found out yesterday my egr cooler is leaking, but the mechanic said none of these would cause the jerking i feel around those speeds. It also spits and sputters in idle sometimes and runs like *** when i i first crank it. Is there anyone who has the slightest idea as to what the hell is wrong with this rag. I havent had it but about 4 months and i am not real pleased as of yet. Any help would be greatly appreciated

 

What kind of preventive maintenance have you done to it since purchased?

 

I have changed the oil and fuel filters(both of them) and i run diesel kleen in every tank. It has been acting up since about two months after i got it.
