Question about 2003 Ford Expedition
I have a 2003 Ford Expedition and I have replaced all the spark plugs during a tune up about 5 months ago and 1 coil. Now the car is dying out and is not accelerating at times. Any suggestions on what it could be?

Replace the plugs and wires (one at a time) to avoid getting the firing order out of sequence. The coil pack the same way. Most of these have clips on the side or either bolts that hold them on. If you do one at a time you'll have no problems.

SOURCE: cobalt no spark
I was going to say crank sensor, but you changed it. What have you done to it latley? Or did this just start? I kinda want to say PCM for some reason. Any welding done on the car latley?

SOURCE: please help
had the same problem in mine we found it was the cam shaft positioning sensor. my van had shut off and we had no current to plugs and at first thought coil pack but still nothing. no power to coil pack. then found sensor no good. also we replaced the sensor with an after market sensor and worked fine for couple months then started to shut off again. after a little research found we needed original cam shaft pos sen from dealer and since then no problems. hope this works for you.
