Expeditions: I have a 200 Expedition...Up until a year it ran

Customer Question

I have a 200 Expedition...Up until a year it ran great.
It now has acceleration, rough riding, shut down issues.
No codes.
Auto mechanic couldn't find the problem. The gas pressure was low so he replaced the fuel pump. He also changed out the alternator, and the computer to troubleshoot, the problem still exists.
Dealer said it was the MAF, I changed it. No change. (250.00)
I looked up information on line and changed the IAC. Little change.
Now mechanic says diagnostic doesnt show anything, and it's probably the computer. Maybe it needs to be re-synced.
Please any help would be appreciated
