2005 FORD EXPEDITION with 85000.0 miles
While driving the vehicle will have not have any throttle response and "check electronic throttle component" shows on dash. After pulling to the side of the road, or coasting into someone's drive-way on a curvey road, turn the ignition off and sit for a few minutes and restart engine and is fine. Has occurred 3 times now, all 3 at speeds less than 45 mph. Took the vehicle to Ford dealership where they charged me $75 to tell me the battery needed to be replaced because that is all the codes that they came up with. Then i would have to return the vehicle to have it checked again. On my description of service codes p-1867-2f, b-1317-2f, B1318-2f, B2477-60, B2486-20, B1318-20, U1900-20, P0121-ff, P2104-ff, P2112ff, B1318ff, were all found.
