Overheating. I have a 98 Mercury Mountaineer. Tonight, the check engine light came on and I checked the heat gauge, and it was hot. I pulled over right away to let it cool.

Engine sputtering I first took my 2006 Mercury Mountaineer to a local Ford dealer for a mis-fire and engine sputtering above 40 mph causing the check engine light to come on. They found and replaced all the lifters and a tune up and it did not fix the problem. I then returned to the dealership, telling them the problem was not fixed, they immediately wanted to do a valve job, I declined. Today they said they wanted to replace the engine and that there was two ports in the head that were clogged
All of the above and lots more. ... 2006 Mercury Mountaineer

I have a 2003 Mercury Mountaineer V6 AWD. Check Engine Light came on - brought it to the dealer and they said the code was to replace the solenoid. Had that replaced and after driving it away, light came back on. Code still says the solenoid needs to replaced. It's been almost a year and the light is still on and I am sick of paying money only for them to tell me they still can't figure it out. I need help!
Replace what solenoid specifically? What was the trouble code? Most parts stores will pull OBD-2 codes for you for free and give you a brief description of what they mean. I would try that then come back here. ... 2003 Mercury Mountaineer

OK so I am fixing my 2004 mercury mountaineer after my bro had left it in new Mexico sitting for about a year. After changing battery, fuel filter, oil and air filter, I started it and everything was fine. When I started to drive it around the service engine light came on. I had it checked at auto zone and it pulled the code P0193. I know it has something to do with fuel but where do I start. Also since this light came on my MPG has dropped to low 9's on the gauge.
