Mariner 4WD 6-cyl

  • 33,985 miles
Driving to work when the wrench light came on and the car started to buck. Then the engine light came on and the car slowed down to 0 when I stepped on the gas pedal. Had to pull over quickly as I was in traffic and shut the car off. Started it up again and only the check engine light was on - car would only go about 15 mph. Found out it was a common problem being looked at by NHTSA. Power train throttle body had to be replaced. Not covered under warranty. I am not a happy camper it was not cheap to fix. Eec test code P2111 I found this on the web and was surprised to find out it has been happening since the model year 2009. Shame on Ford.
