2003 mercury mountaineer 4.6l-v8: when the vehicle is not under acceleration [stop sign/signal, exiting an expressway to a surface street, coasting] the engine will not hold idle, then stall. The steering & brakes are compromised when the engine stalls. To restart the engine, the headlights go dark for a moment...this is a very serious matter. Decelerating from an expressway to a surface street, on a curved exit ramp , at night makes for an out of control situation where the driver can not see because of engine failure! I've replaced the throttle position censor [tps] with no improvement. The dealer offers replacement of parts $1500, and no guarantee of solving the problem. The vehicle is useless to me fore it is a hazard to be on the road...for me and anyone else driving near me.

My 2003 mercury mountaineer would stutter and have a jerking motion like it was going to stall and it would do this at any given time. On the 13th of january I was taking my youngest daughter to school and my car started to stutter and then it just stalled on me I had a difficult time starting the car. I then took her to school and I shut the car off to walk her to her classroom and then got back into my car and when I put the key into the ignition and turned the key there was no power my car was dead I had to call the road side assistance number and had to wait an hour for a tow truck. I was told by the dealership that it was the instrument cluster head and it was fixed and I was not given a rental car and I only had this car 11 months. Well two weeks later as I was getting ready to make a left turn on a very busy intersection my mountaineer stalled on me once again and all I could do was pray that it would start it took three tries to get it started and I drove it down the block to the dealership once again and made them take the car. Well they had my car for another four days and I was told once again it was the instrument cluster head. Then in february of 2005 the ford dealership wanted to do a run down of my car to make sure it was fixed but low and behold I have to take my car back on april 5, 2005 for the same stuttering and stalling problem. I feel that this car is a lemon and unsafe for my family.
