2005 Ford Expedition Q&A

2005 Ford Expedition Question: Skipping 3-4 times

I had noticed before a skip going up small hill 3 or 4 times. I just recently had to get a new transmission. This was a problem before I got new transmission also. What would cause this? We also replaced the throttle body. -
Answer 1
Coil breaking down! Scan test needed to find which coil as there are eight total. -
