My '99 ford taurus has been having several problems lately. The car does not want to start, and when it does, I am forced to keep putting gas into it in order to keep it from stalling. When I shift between reverse and drive, the call stalls out. It also stalls while at stop lights or intersections. It does not want to idle more than 300 rpm and when I accelerate, it can jump up to 5000 rpm before I even hit 35 mph. It has a little more than 154,000 miles on it. I just put half a bottle of oil in to insure that the oil level was proper. I have seen this problem in the past during the winter. It is still warm where I am, and I do not think the car is cold. Any thoughts?

It sounds like a bad idle air control valve. Has the check engine light come on? Also, have you checked for vacuum leaks?

As far as the RPM's, isn't the trans shifting?

The check engine light has come on. It came on yesterday and the oil light came on today, but then went away. I'm not sure about the transmission. I was told by a mechanic that the 99 ford taurus has a poor line of transmissions. Sometimes when it runs at a very low rpm, it will suddenly jump to extremely high rpms and the car will suddenly jolt forward.

The check engine is going to help. What I need you to do is take the vehicle to a nationally recognized parts store and have them scan the computer for trouble codes. Most will do it for free. Let me know what code they find. I feel it has something to do with the idle air control valve, but I can't be 100% sure without a code.

Thanks Joe. I took it into Firestone today and they should have a diagnosis for it tomorrow. I will keep you informed.

Let me know what they say. Don't jump into anything until I hear the problem. Ask them to tell you what trouble codes they pull. I just finished dealing with a man that was told he needed a new engine when all he needed was a 20 dollar sensor. That really is upsetting to me.

Well, they told me that my idle control valve was very dirty and sticking. He also suggested that I have a new air filter put in as well as have my fuel injection system cleaned. Finally he said that my car needed to have a fluids check. I think that sounds somewhat reasonable.

That doesn't sound out of line.
