get the code read and post it so we can try to help you.

Autozone or a similar place will read the code for free. Find out what the code is, then post in on here and we can tell you. Make sure you find out the code exactly, not just a cliff note of it. We want to see P0125 or something like that.

Isnt that a cylinder misfire code. Maybe check your plugs and wires.
