2004 mercury mountaineer experiences loss of power, running but no acceleration
What is your question?
The 2004 mountaineer will loose power coming to a complete stop, if you are on a hill it will suddenly roll backwards. Engine still running. There is no warning. No sputtering, nothing.
It will also sometimes just stop running, therefore no power steering or brakes to assist in getting off the road.
If it is put in park key completely turned off, it will restart and have power. These may happen one time in 35 miles or up to 30 times in 35 miles. It seems to be more frequent on warmer days. But getting to were weather doesn't matter. No mechanic had been able to figure it out.
What makes this problem better or worse?
Little worse in weather over 75 degrees
How long has your 2004 Mercury Mountaineer had this problem?
Since purchase in 2014

Hello, it's really hard to know exactly what you are experiencing and what direction of diagnostic testing is best to go in. It would seem that your vehicle engine performance is an issue - either with fuel, spark or air intake causing loss of engine power or even a stall. It's too hard to know without seeing exactly what is happening and what the data shows when that happens.
A shop near you can really help.
