2004 Mercury Monterey Vehicle speed control Problems

“It is a well cared for 2004 that all of a sudden started to have a little shake when accelerating. Once I got up past 50-55ish it almost went away. I assumed I had a wheel out of balance so when I had it in for an oil change a few days later, I had them do a rotation and balance. That really didn't fix anything and it got worse.

Since the repair I have continued to experience problems with drivability. Gas mileage has reduced greatly (was around 17-19) down to 13.8.

I continue to get that they can't identify a problem.”

I'm afraid that this electrical problem will soon cause a fire of some sort.”
