Driving Slow

Car Information:
Ford F-250
Year: 2004
Engine Size: 6.0 Diesel
Trans: Automatic

Issue/Question: The engine seems to run fine until I drive at slow speeds, feathering the throttle while in traffic. The idle increases, and the engine surges sometimes up to 1500 rpm. Then it falters and runs really rough. Then sometimes it will just quit altogether. The problem sets no codes in OBD and I’ve been running the scanner during the episodes with no code either. I’ve had this to Ford 3 times and they have replaced thousands of dollars in parts but cannot solve the problem. The engine is now out of warranty. I have gone through 55 pages of info on Edmunds.com and find many similar symptoms but no one has offered a solution yet. I’m now afraid to go out on the road towing my RV trailer with this thing. I can see why they call this a “Power Stroke Diesel” because that’s what it gives the owner. Can you help me? By the way I really enjoy your show.

Answer:
Their’s a oil supply line that feeds the injector system inside the motor, if the line leaks off pressure it will stall the motor like you describe. We will need to take an oil pressure test at the injector oil supply to verify if that is your issue.

1997 Ford F250 HD Brake Problem

Car Information:
Ford F250 HD
Year: 1997
Engine Size: 7.3 diesel
Trans: Manual

Issue / Question:
Six months ago, I replaced the brakes in my vehicle. However, the other day I stepped on the brakes and the pedal is very resistant. My question is, did the power booster go out? Is there some way of checking it?

Answer:
If the power steering still works, the hydro boost system may have failed. When an accumulator goes bad on these, it will cause this problem.

Oil Pressure Drops When Engine Is Hot

Car Information:
Ford F250
Year: 2001
Engine Size: 6.8 l v10
Trans: Automatic

Issue / Question:
My truck’s oil pressure drops to zero after it has been running for a while. When I turn off the truck and then start it back up again, the oil pressure is normal. The pressure only drops when the engine is hot.

Answer:
Sounds like the sump is getting plugged up with sludge. I would recommend running a mechanical oil pressure test first. If it starts to fade at 2000 rpm after running a while, the oil pan will need to be removed and the sump and pick up screen inspected.

Stuck EPC

Car Information:
Ford F-250
Year: 1997
Engine Size: 5.8
Trans: Automatic

Issue / Question:

It shifts really hard at 10-15, 20-30, and 45mph. Just recently replaced the trans filter hoping it would help but it didn’t.

Answer:
Sounds like a stuck EPC electric pressure control solenoid. If this sensor quits working, it wont exhaust the fluid to control pressure. And if it doesn’t it will shift really really hard! Let us know if you want us to look at it.
