you need to get the coil wiring replaced as well as the spark plugs on the cylinders too. And also the air filter will need to be replaced as well. Have them do a diagnostic on the Check Engine light to see if that is the problem. More than likely it is the problem. It will cost you close to $800 to get this problem fixed. If you take it to a cheaper mechanic, then you will pay around $400 or less.
Also it could be the air filter needs to be replace as well as the gas filter too. That will cost you about $300 or so. Also get the car tuned up too.
