My car seems to be missing while i'm driving it or sitting idle. My dad is attempting to check spark plugs however he seems to be having a hard time. Also the check engine light is on while it's sitting idle & while driving it blinks.

The check engine light flashing indicates that a misfire (one or more of the cylinders is not firing) is occuring. This can be caused by the spark plugs, however, there are many different possible causes for misfires. To ensure that parts are not replaced unnecessarily, a diagnosis should be performed by a professional.
