Question about 2000 Mercury Mountaineer

1 Answer

The 2000 mountianeer starts and runs fine but shuts off

The 2000 mountianeer starts and runs fine in warm weather, 50 degrees or above. In colder weather it will start but it will not sit and idle and stay running, it just keeps cutting off until it is completely warmed up. You have to keep starting it and sit with a gentle pressure on the accelerator if you push the accelerator to far it cuts off. Once you can drive it a few miles, usually taking off requires using both the accelerator and brake at the same time, it runs just fine. So therefore it runs great about 7 months out of the year until the weather turns cold. A mechanic replace a few pricey electronic parts last winter but it didn't seem to help.

I have a 2000 pontiac grand prix with a digital climate control system. The heat quit working, it doesn't blow out any heat. Now that it is warm outside the air stopped blowing out any air. The digital temperature on the climate control is not correct. When it states that it is below 30 degrees on the ext and it is warm outside the air wont be cold. Once it starts going above 30 degrees the air gets colder. Today the blower stop working all together. Was told it maybe the climate control unit was bad. You can hear the door opening/shutting when you switch the temp from cold to hot. But there was no heat blowing out whatsoever in the winter time. Could you please give me your opinion on whether or not it is the climate control unit or something else?

2000 VW Beetle will not start in cold, runs fine above 40 degrees


I was just reading the owners manual for my 2000 beetle and it says the diesel fuel has a problem with the wax separating from it below 40 degrees. Put the car in a warm garage and it will start.

Engine will not idle and run when starting in cold weather


Have a mechanic take a look at your throttle position sensor and engine idle sensor. Make him manually adjust them as opposed to just putting in new ones. It may require that you have to have a higher idle than normal. Your underlying cause is going to be that I am sure you have a lot of miles on your engine.
