When accelerating the vehicle would be rough and inconsistent almost lurching forward at times. The vehicle would do this every time it was driven. After having to replace the vehicles battery the vehicle would not accelerate at all. The rpms would not go above 1000. The throttle body was replaced and now the vehicle drives fine. I do still have the old part.
Our 2006 Mercury Montego lunges, and suddenly accelerates with no foot pressure on the gas pedal. It is clearly a missed recall with issues with the throttle body. Ford knows all about this issue and so do you. . . . . Read more...
First at 56k miles when putting the car into reverse it wouldn't go into gear, under warranty Ford changed the fluid said nothing else was wrong, got car back and it still did same thing, took back to Ford nothing wrong but car continued to have same problem and a the motor noise got louder. Then at 112k car wouldn't go into gear, high speed was 10mph. It was the cvt transmission. Called numerous transmission garages no one works on them. Found one that would look at it, they confirmed it was the transmission, Ford would not release any parts for rebuilding it. Then Ford would not release a refurbished transmission for it, then they claimed the garages just had a miss communications. Called Ford customer service, they said call back in 48 hrs had to call them back a wk n half later, just to be told by kim the supervisor that she hopes I have a nice day. Ended up paying $6800. To have my transmission replaced with a refurbished one from tenn. Had to pay xtra shipping. Ford quit making the cvt because they know the problems that it has and is not standing behind their error.
Ac blows hot air when vehicle is not moving. If you are moving slow or stopped at a signal light or stuck in traffic the ac starts blowing hot air. It works fine as along as I am moving.
