I was driving when it felt like the vehicle was reving in park then the "wrench" icon appeared on my dash. I went a couple blocks & my vehicle felt like it wasn't shifting automatically as it should. I pulled over & turned it off. It started right back up with no lights on, I went half a block & stopped at a stop sign but while stopped the engine reved up. I was worried I was going to be in an accident. Then the "wrench" light came back on, since I was close to home I figured I'd just try to get home. About another block, the check engine light came on & was making strange noises. I kept my vehicle at about 5-10 mph & got it home. My car was very jerky.

Having two issues. The first one is the check fuel intake warning light comes on and my check engine light stays on. This appears to be causing my car to cut out dangerously at intersections as well as the wrench light to come in and my car 'limps' home.

When intering to tunnel my car suddenly speed up it felt like I had the gas pedle down to the floor. Even while holding the brake all the way down, this did not slow the car down much. There were no warning lights or check engine lights on then or now

I was driving my 2010 mercury mariner premium fwd to my mothers for christmas '14 when the engine light wrench came on and I felt a loss in power. Luckily I was near a rest stop and I shut off engine and let it sit after running a vehicle health report. Report said: urgent power train malfunction / reduced power. After restarting the vehicle, it seemed fine. This was when I still had about three hours left of driving in my eight hour drive. When I was about an hour away again the light came on and the same power reduction occurred. I took it to be looked at to the local ford dealer near my mothers and was told the valve body needed to be replaced. This was at 74,000 miles. So I did. I had this happen once before (I had 58,000 miles on it) when driving to a shopping center after driving 45 minutes on the highway from home. Only happened when driving long distance. When I got off the exit, it jerked and quickly stopped and I had to pull over. If a car was behind me it could have caused an accident.. I drove it to the dealership and was told that I had a couple recalls (computer updates) and a service extension for the throttle body. Should fix the issue so it won't happen again said the mechanic. Transmission fluid was flushed cause it was burnt also. Had no issues afterwards until my christmas trip. I feel I could have been in an accident and seriously hurt if it had jerked while changing gears on a busy road. I would like to know why there is a throttle body recall but not a valve body recall? If these issues can cause a quick jerk or lost power causing a quick slow-down, seems like there should be a recall for both. It appears I am not the only one with these types of issues after googling the issue. Seems like its time to get these transmissions fixed correctly before someone is killed or seriously injured! Please recall now b4 it's too late!

Coming to a stop at a red stop light and then trying to accelerate from red to green light at an intersection my vehicle went into limp mode, it lost power. It would not accelerate pass 10mph. An engine light came on as a orange wrench light. I drove as I could and made to auto zone. They plug in the hand held car computer and it gave the code p2119. Which stands for throttle body.
