I have a 98 Nissan Altima I just got done 3days ago replacing the valve Pan cover gasket spark plugs and spark plug wires and even change the oil and oil filter before i went back over the road . Now she tells me shortly after I left she noticed the check engine light cap coming off and on now the motors knocking. Does anyone now what can be the problem ?
