First thing first, scan your computer for codes, you can use a paper clip or short piece of wire plug it into A and B of your diagnostic port under the dash, it should be the first to on the top right of the plug. Go from there. In case you don't know how to read the codes, no offence, your check engine light will light in short bursts. The first code will always be 12, one pulse pause two pulses. It'll do that three times. then if there are others it will do them after that. It'll run through the codes three times and start over with 12 three times. Then you can just get back on here and I'm sure someone will know the codes.
