- 1998 Mountaineer AWD
I have a 1998 Mercury Mountaineer with the 5.0, approx. 225,000 miles. Has, for the most part, always been very dependable.
Sometimes, however, particularly on a hot day, it begins to run very rough. This mostly happens after it is left idling for a while, such as waiting in line at school to pick the children up or if I run into a store for just a minute while the wife waits outside with the motor running and the air conditioning on. This also happens when we go to town and are in a lot of stop and go traffic.
What happens is, it begins to run rough and seems to bog down at first. Then, it either clears up or then it gets worse and dies. The other day it died while leaving the grocery store and I basically had to let it sit for a minute or two before it would crank back up. It will seem to start missing and then acts like its flooded and then sometimes lets out a little backfire when it gets going.
Anyone experienced this or have any knowledge of what could be going on here?
