Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

Mariner 4WD 6-cyl

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.
