    I have been having this issue for a while now... Under load at higher RPM's (most of the time on interstate above 55 mph) I have an occasional misfire. Sometimes it's several misfires with in a few seconds of each other...other times it's just one and done and like today there wasn't any issues at all... I did notice a crack in my exhaust manifolds...could this be causing any issues?? Can I repair OR should I replace?? OEM or aftermarket??

    During the hottest of summer days after running earnings/city driving if I turn off the motor it is very hard to start compared to cold starts or all winter starting
