2006 Mercury Mountaineer: engine stalls while driving

Filed Sep 7, 2017 · Engine, Fuel system · 42,000 miles · MA

I purchased this vehicle recently with only 40,000 miles. The car keeps stalling or dying as you may say as I drive. It will be okay for a short period of time and then just die right on the highway! Once it dies once, the car will continue to do so over and over again until the engine has cooled down. I have the engine codes of p2104, p2111 and p2135 with a refere to p2101. I have brought it to several mechanics and paid well over $1,000 to fix this problem and it just continues. I am afraid my family may all die! Were on 93 recently heading toward boston and my car died right at the intersection of 495. I had all my children in the car and it would not restart. I have fixed the fuel system (error code last time), had a complete tune up, and throttle sensor etc.

2006 mercury mountaineer driving along around town or highway and will just loose power without warning after the fact then the engine light comes on along with a red wrench or an orange wrench, first place I had it to said it was a negative battery cable that was loose so they tightened the cable, took it home stalled out on me, took it to another dealer said was reading that it was the fuel pump driver module drove very next day stalled on me once again taking it to the ford dealer itself said could be a number of things one is that the mass air flow has exposed wire which they will be fixing that and cleaning out the electrical throttle body and see how that is if not then they will try replacing the torque convertor clutch circuit for one this needs to stop being a guessing game I'm not a millionaire I used my 401k to purchase this vehicle, its such a huge safety issue while on the main highway and just up and stopped on me luckily I was able to drift over to the side of the road in the meanwhile with a tractor trailer coming up behind me with several other traffic huge safety concern ford contacted by the one garage and they "wasn't sure" what it could be, well it stops anytime while driving anywhere such a huge safety hazard someone has to know something without having to just "guess" the situation. Also every time it rains the water seeps thru the sunroof and the overhead light you can see it came thru the liner itself when it dries up, so heartbreaking because I fell in love with this vehicle that I have only had for about a year and half.

Tl* the contact owns a 2006 mercury mountaineer. While driving at approximately 55 MPH, the vehicle intermittently stalled without warning. The vehicle was taken to an independent mechanic, who diagnosed that eight spark plugs needed to be replaced. The vehicle was repaired, but the failure recurred multiple times and a coil pack was placed to prevent the spark plugs from blowing out. The manufacturer was not notified of the failure. The approximate failure mileage was 105,000.
