I have a 1998 mercury mystique. The vehicle recently began running abnormally. So in inspection of this, I discovered that the vehicles acceleration is being raised without me even touching the gas. I was on the road and my vehicle was speeding up on it's own and I couldn't figure out why. It seems as if the cruise control is constantly on or something.

What owners say
Cruise control cable linkage got hooked onto the bleeder causing the throttle to stick. The dealer has been notified. Nlm
While traveling cruise control sticks, not disengaging set at 65 MPH. Owner pushed brake pedal to disengage, but no response. He then tried pushing off button on steering wheel, still no response. Owner had to immediately pull off the road and shut off ignition. Vehicle sat on the side of the road until owner felt that vehicle had cooled off. Then, and only then, was he able to shut off cruise control. Owner stated that manufacturer was reluctant, and did take complaint seriously. Please describe details.
Transmission problem has been analyzed several times by both ford dealer and other shops. They feel solenoids internally have failed and transmission must be rebuilt/replaced. Vehicle does not shift properly, will not go into overdrive (4th gear). Loss of cruise control. What shifting remains is erratic. Speedometer gear drive sheared off and was replaced before full extent of problem became known. In reading on the net about other people with same problem, appears solenoid failure in this transmission is common and premature.
While driving at 65 MPH with cruise control engaged consumer attempted to hit brakes to disengage cruise control and slow down, but vehicle speeded up, lost control, and hit a guardrail. Consumer has yet to contact dealer. *ak
