It could be a cam timing issue. If you manage to move the timing gear on the crank it will throw out the cam timing and make the car run rough. It usually happens if you drive the car hard. other than that if you have the car running and pull the ignition plugs out one at a time you should notice a difference. If you pull one out and there is no difference then that cyl has an injector or coil problem.
