Misfire
I have noticed a missfire on my 95 Lt1. I changed the plugs and it still persists. Last night we finally had a nice night, so i took it for a ride to see if it continued on a dry day. It was worse. Also, a "SYS" code started to flash where the milage normally is. Today i found plug wire 5 has rubbed through the coating to the wire. Would this be the problem or does the "Sys" mean somthing else? Anyhelp would be appreciated. thanks in advance.
