Weird problem that just started up 2 days ago. I drove from Miami to Orlando and when I got to Orlando when I was at red lights my engine started sutterting and being real jerky at idle. Once I got to 30 mph+ though it smoothed out and was fine. Drove back to Miami the next day and same thing when I got to Miami and was idling. I called in to one of those radio car talk shows and he said it was probably a bad vacuum which was why the problem dissappeared at higher rpms and speeds.

Taking it in tomorrow to a shop but wanted to get your opinions on if this is reasonable and if there were any other things it could possibly be.

Also wanted to note that my engine light didn't come on the first day but today it was started to stay on. I don't know if its the check engine light but its a red light with a picture of the motor.

Thanks guys.
