wrench light came on and car lost power. had to pull over and cut off car and then restart. had a hard time starting back up. starting to happen frequently.
Wrench light comes on, then after a while the vehicle will start running poorly. The engine will loose power and not accelerate. I have not yet fixed this issue.
need a new throttle theu quoted me a price of 871.00 Ford stated that this is a major problem for these cars, i think it should be a recall, why should we have to pay when Ford knew the part was bad.
Yesterday morning theCheck engin light came on. cruise control stopped working, and it began shifting erratically. in the afternoon it worked normal. this morning i hade the same symptoms. i turned the engine off, then restarted it. everything worked normal
Wrench light came on. car stalls, doesn't seem like it's getting any gas. needed to replace the throttle body for $640
Engine surges when placed in Reverse or Drive, have to keep my foot on the brake until the surge
idles down. Almost hit this poor guy on his bike while at a stop sign. He passed in front of me and I had my foot on the brake but received this sudden surge, lunged slightly forward, scared both of us, he just looked
at me like, "are you trying to hit me"? Spoke to this guy that works at Ford of Port RIchey,Fl. and he told
my husband that the maker of these throttle parts, is the same maker of the part that went wrong in the Toyota's that had the sticky throttle causing so many accidents. Ford needs to send a recall out before someone
gets seriously injured. Price to fix my issue, $530.00 for the part and another $300.00 for labor,,, ohhh yea!

check engine comes on once in awhile, but goes off by itself, maybe a couple days later. When I had the code checked, it would be something with gas cap. Cap is always secure, the light just ends up going out on its own after a couple days.
Not fixed yet. The car stalls once the wrench light appears. Purchased as used vehicle as it was a mint condition car on the lot. Now, I know why. I am back to driving my 1998 Honda Accord with 270,000 miles. I feel so safe in my Honda!! UPDATE: According to the diagnostic test that was recently done it is the Throttle Positioning Sensor that needs replaced. Dealership has agreed to split the cost, $500 part and no repair fees. I will pursue this further but not with dealership. I have never had to spend this amount of money to have my Honda serviced or a part replaced. Since the vehicle no longer starts, it is being towed to the dealership since the part arrived. I am fortunate that I never encountered this problem during rush traffic. I will be excited to see how the vehicle performs. I will follow-up. Question: Now I am confused, so possibly it is not this sensor but the whole throttle body? UPDATE: After waiting two weeks for the part to arrive at the dealership since having the Throttle Positioning Sensor replaced three weeks ago - thus far the car has been perfect. The dealership split the cost with me. I hope this is the end of encountering any other problems except for the preventive maintenance.
Throttle Body Sensor. Since having a new sensor installed this past March, I have not experienced any other problems. The dealership split the cost of the part $500 and no labor included.
Wrench light comes on, car loses power and is jerky rough ride limping slowly along. Replaced Electronic Throttle Body in July 2012, cost over $800.00. Same problem again in December 2013, had Electronic Throttle Body cleaned. Same problem again and had ETB replaced again on Jan. 26, 2016. Just had same problem again today Feb. 9, 2016 but Ford dealer could not determine what's wrong but charged me $99.00 to check for codes. I will never buy a Ford again!
Have the same problem with my 500 dealer says the throttle body needs to be replaced needs it you be a defected part
Car does not immediately respond to throttle then lurches forward. problems maintaining speed, and engine shuts down causing everything (PS,PB) to shut down. Almost crashed.

I was told that I needed a throttle body unit. Upon researching the problem, I found that this was a common problem that could be corrected by Ford.
Wrench light came on indicating throttle problem. Feels like car does not want to accelerate. It slows down and loses power. I did get home and looked in my owners manual. After reading all these posts, kinda scary. This should be a recall. I am going to my mechanic first before I do to the dealer. I don't trust the dealers, I've heard to many stories. I will keep an update. My car was fine when I drove it this morning, but I don't feel safe.
My torque wrench light came on and I lost acceleration on the car I pulled over to the road turned it off turned it back on and it lwemt anyway. When I have acceleration issues it's only when I'm going more than 50 miles an hour if my torque wrench light comes on when I'm driving in the city I don't have to stop
