| My check engine light comes on constantly in my 08 F250 6.4liter Powerstroke. I took it to the dealer, they said to drain the fuel/water separator. I did and the light went out. I have been averaging 10 mpg towing 10,000lb. I went to Circleville, Ohio with my trailer empty and my check engine light on and got 7mpg.I drained the water separator 3 times but the light never went out. I loaded a 7,000lb truck on my trailer, the light went out and I got 10.2mpg on the way back. I have 45,000 miles on the truck now. Has anyone else had their check engine light come on constantly? | |

| ford just released an update for 6.4L engine computer. It gave my brothers 2008 f250 an extra 150 km a tank.I installed a k&n air flow kit in my 6.0L 2006 and was getting an extra 200 km a tank higway. I will be installing a roush cold air intake in my new 6.4L 2008 next week.I will post the increase in fuel mileage. The only other add on I can think of is duel exhaust. | |

Replying to: 2scoobys (Jan 09, 2009 8:18 am) '' What is the issue?'' ''Your vehicle may exhibit drivability concerns, including elevated idle during DPF regeneration,minor cruise control speed fluctuation,automatic transmission shift quality (if equipped) and a false check engine indicator light.'' I thought the cruise control fluctuation was caused by a lack of power. It doesn't flucuate until you hit a hill. Maybe, hopefully they will turn the power up closer to what they said it is supposed to have. I have a Ford Performance Trucks magazine that dynoed the 08 F250 and showed a stock 292hp. and 286lb-ft torque. That is a far cry from 350hp and 650lb-ft they advertised. By comparison the old 7.3 liter powerstroke showed 184hp and 388lb-ft. It takes a heavy load to affect the cruise on it. This should not be! |

| My '08 has a leak just under the front bumper on the passenger side. The fluid appears to be clear, grease less, oderless, and colorless. Today I noticed the coolant overflow container was bone dry. Anybody having issues with this. I need advise! FYI, I was told my '08 had a special recall for a radiator stop cock valve. This was executed about 2 weeks ago at my dealer, Rancho Santa Margarita Ford, here in Cali. I recently read that some contributors hear on the forum had jettisoned engines from what was suspected as radiator leaks. Your input is greatly appreciated. | |
