Why is my Ford Expedition sputtering?
Fuel injector nozzles can become clogged over time, which can lead to a sputtering engine, slow acceleration and the car not having enough power. If they are not working correctly or are dirty they don’t ignite the fuel cleanly and the car can misfire or sputter. The plugs will need to be replaced or cleaned.
Why does my Ford Expedition keep shutting off?
If the torque converter is broken, or if there is a low fluid level in the transmission, the converter will not do its job, and the car will be unable to maintain power at low speeds, which causes the engine to shut off. A defective TCS or torque converter solenoid can also cause this issue.

Why does my Ford Expedition stall out while driving?
It now stall out 10 minutes on the DOT after starting… after idle or driving. That tells me its not mechanical and must be something electrical getting hot and shorting out or losing contact. Usually its starts back up and I floor it to wherever I have to go with no problems but past two weeks it wouldnt start back up and had it towed twice.
Why does my expedition not accelerate when the RPMs go up?
If your Expedition won’t accelerate, but the RPM’s go up it’s usually not going to be an engine related issue. Somehow, the power that your engine is creating is not making it to the rear wheels. This is typically a transmission related issue. Here are the most common cause of acceleration with the RPM’s going up:
Why is the timing chain on my expedition not working?
The timing chain (or belt) is responsible for keeping the upper valve train synced with the crankshaft. This is vital for spark timing. If the timing is off a little and the engine still runs, the timing belt may have skipped.
