Recently, the pcv valve in my 2002 mercury mountaineer had a leak (vacuum system leak). As the vehicle began to stall as a result of this leak, while traveling 55 MPH, and decelerating towards a traffic light, I lost all function of my brakes. When I stepped hard on the brakes, there was no response. However, because I equated this to possibly being tied to the pcv valve, I stepped on the accelerator to increase airflow into the engine so that I would have brake function. This gave me brake function, temporarily. However, this move was very risky, as I was approaching cars in front of me and accelerating towards them instead of decelerating, just so I could slam on the brakes and have functioning brakes. There is an apparent link between the brakes and the vacuum system...which poses a deadly situation. Had I not been aware of vacuum system issues and how to mitigate them, I would have plowed into the stopped vehicle in front of me with no brakes. This occurred in the evening. I had to use this method to complete the remainder of my trip to get home, accelerating every time I needed to use brakes, because the stalling vehicle every time had no brake function. This condition put me in a very bad situation, as I also had my 5 year old in the car with me. This system should be recalled as it is unsafe. Replacing the pcv valve corrected the problem. There is also no notice in the operating manual for this vehicle about this vacuum system problem, especially since the operating manual that came with this car is for a prototype software system, and doesn't even match my vehicle. I have complained to mercury/ford about this incorrect manual, but they did not offer to send me a new one, and simply took the information and didn't even respond to my concerns.

I was driving home in my 2002 mercury mountaineer on monday evening in lyndhurst, nj around the time of 7 pm. I heard a very loud bang, followed by some rattling which scared me half to death. I had no idea what has occurred. I was very nervous because I was unable to apply pressure to my break to stop without the truck idling very rough like it wanted to stall. The truck lost all power. I carefully proceeded to a local gas station in rutherford and dropped my car off for the machining to look at in the morning. I received a call the following morning from (the mechanic) who stated the #5 spark plug ripped out of my aluminum engine head. For a cost of $366.00 he re-threaded the spark plug, installed a new coil and did a tune-up. He told me this is a very common problem with certain v8 and v10 ford engines. It can occur again, or the same plug may rip out again. This is a very dangerous situation especially when I have to go on two highways to get to work everyday. The sound was like I was being fired on by nato. Imagine losing power on the highway with people behind you at 65 MPH. I looked on the internet and found many compliants by ford customers who had the same thing happen several times, causing them to replace the engine. Ford does not want to take responsibilty, someone needs to make them replace these dangerous engines. Spark plugs just fire the engine, they are not supposed to shoot out of the engine like small rockets. What if my hood was open and this happened? Someone could have goten killed. If this were a baby seat, crib or child toy it would be recalled. We can't wait till there is a death from this problem.
