Ok So my check Engine light turned on today but my car seems to run fine until i was on my way home when i came to a red light and as I slowed right before I came to a complete stop the car started jerking a little and when I was stopped It idled funny, like i't go from 500 to 900 then drop back to 500 and repeat itself. Any ideas what it might be or if theres anyway I can diagnose the problem?

its a vacuum leak. i had the same problem on my 98 ford contour. come to find out there was a rubber plug missing off the intake plenum... chec your hoses

A Vacuum leak you say, I'll check my hoses tomorrow, hopefully that's all it is.

Ok so I checked for any lose or other wise damaged hoses nothing. I decided it seemed safe to drive my car. After putting gas and driving for a bit the Check Engine Light turned off and hasnt came on since, Any clues?

what was the gas level when it was idling rough, what did you fill it up to

It sounds like your charcoal canister, but could also just been bad gas from the bottom of the tank

did you get the code off of it? if you did what was it?

well my friend has a Scanner I was planning on using but the light went of before I could get the code. I had around a quarter tank and I filled it up. My dad always said I should have changed the fuel filter I just kept putting it off. guess I should change it while i have the time
