Would love your help in the problem of our auto running rough after maybe getting bad gas. After getting gas the car was running very rough and sometimes knocks like its not running on all cylinders. They did a diagnostic test and said the number 4 cylinder was not firing correctly. Would this be a bad plug and if all were replaced would this maybe solve the problem of the knocking also. Thanks for any help
