I have a 1998 ford contour and every time I have to brake hard like a sudden stop my car engine revs hard jerks then shuts off and the oil light comes on. When I turn the car off then on again everything is fine. Also my car rpm fluctuates and jerks in the morning when I start it up.
Do you
have the same problem?

Hello stef909-

Check oil level. If low add some.
If the oil is dirty, change it together with the oil filter.
What oil grade you're using and what is the weather where you're living.
If there is engine light, have it diagnose with a scan tool.
If there are other things you forget to mention, please let me know

Well I live in Delaware and its around 45 degrees now. I dont no what kind of oil it has in it at the moment because it was a used car. I just dont get why it shuts off when I brake hard.

Hello stef909
This kind of stalling problem often means the engine is not getting enough fuel and/or too much air. A cold engine needs a fairly rich fuel mixture to start, and to idle smoothly while it warms up. Rpm needle should not fluctuate at idle and that means you have a vacuum leak.
When you brake, the throttle is close, only the idle valve is open same as when you first start the car and the rpm needle jerks.
Check for loose or broken vacuum hoses, leaks around the intake manifold gasket or throttle body.
Check around the PCV valve, EGR valve and the IAC valve.
Check the battery for low voltage. It can adversely affect the operation of the ignition system and fuel injectors, causing stalling and misfiring. A good charging system should produce about 13.5 to 14.5 volts at idle.
