Low compression caused by leakage from exhaust valves can cause the check engine light to illuminate indicating an engine misfire. The cylinder head will need to be rebuilt by a qualified machine shop if possible. Please note that this problem will require careful diagnosis because misfires can also be caused by basic ignition components like spark plugs, coils, etc.
