1997 Ford Expedition my truck

Hi:
Fuel pressure can cause problems but not a steady miss. Is the check engine light on? One of the most common problems is coil pack problems. The injectors are quality and rarely malfunction.

You can check to see if the fuel pump is working properly. Go to our website:

Ken, one the master technicians here at 2carpros, has a video that shows how to check fuel pressure using a gauge. Also, most nationally recognized parts stores will rent or lend the gauge to you.

Let me know about the check engine light and if the engine is a 4.6L or the 5.4L.
