Can anyone have any ideas why my '98 gt has a miss sometimes usually happens when first start it but has happened a couple times when driving also ;when it happens if i turn it off and restart it in a couple minutes it's fine and it will go about a month then it does it again it's the weirdest thing check engine light doesn't come on when it happens either I changed the plugs thinking it might be a plug acting up once in awhile but it did it again since then .HELP!!!!!!
