Engine Performance problem
1996 Buick Regal 6 cyl Front Wheel Drive Automatic

When started cold seems to rev up and down sometimes and seems to not idle right when sitting at stop lights. Also runs good on highway buts seems like it bogs down when you light off gas pedal and also fuel mileage seems to be worse.

Has the check engine light come on? Have you checked for vacuum leaks and to make sure the catylatic converter isn't plugged?

If the check engine light is on, I need you to do something. The light indicates there is a trouble code stored in the computer. I need to know what that code is. Take the car to a nationally recognized parts store and have them scan the computer. Most will do it for free. Once you determine what the code is, let me know and then I can direct you toward the problem and how to fix it.
