1998 Ford Contour "Stalling"

One of the first things I would check would be vacuum lines for leaks. This would show adverse effect when the brakes are applied, and when it is put into gear.

Start "dry", with a thourough visual inspection of the lines and the plastic ends and connectors. Check the intake manifold as well, as this is where the cycle for the vacuum is started. If you do not see a rubbed spot, loose end, or anything else that is supect, grab the safety glasses. I use a cleaner called Chemtool. With the engine running, and all safety gear in place, carefully spray down the intake gasket area, and all the vacuum lines you can reach safely. If you have a small leak, it will run the rpm's up a bit. If you have a large leak, it will kill the motor.

Best of luck with your repair.

:D Could it be the transmission maybe?
