Engine Performance problem
2007 Ford F-150 V8 Four Wheel Drive Automatic 53189 miles
I have been fighting this for 2 months now. My Mechanic & 2 Ford Service writers do not know what to make of it.
So far I have heard of several people having similar issues but no one has posted any updates for what the fix was.
Once warm, The Engine will buck or hesitate, usually when maintaining cruising speed or sitting at a light in Drive. When out of gear it idles Smoothly, When accelerating it is smooth and after the initial moment has a lot of power.
Once in September I had a message come up on the com that said " Running at reduced power", Everything seemed normal and It quit a minute later and never happened again.
I have had the injectors cleaned, Changed the fuel filter, Air Filter, Ran 2 tanks of high Octane all to no avail.
Scan showed that 1 cylinder ran hot 1 time, but no other codes.
