I had a Lebaron once and the MAP(manifold absolute pressure)sensor did the same thing on it .Depending on the vehicle this could be an internal (more expensive ) or external. Saw a guy at a gas station once , he filled up and car wouldn't start I mentioned MAP sensor . Saw the guy a week later and it was the sensor but on his volvo the sensor was apparently internal.$600 fix for him and $50 fix for me.
