check engine light

you need to get your trouble codes read, either from a major autoparts supplier or buy one yourself for around 40-50 bucks, but once you get the data for example P102, please tell u so we won't have to guess at whats wrong with your buggy~

yes indeedy. sounds like a misfire, when the CEL blinks that indicates misfire and the engine running jerky. but yes you need to get the codes read and probably need a good ol' tune up
