what does your AFR look like right before the misfire happens?

also if your clutch is slipping, your RPMs will quickly shoot up but you won't go anywhere...it'll be easy to tell if it happens

 

that sounds like a vac leak or bad tuning to me

like ionninja said revs will shoot up to redline as soon as the clutch slips and you wont go anywhere

 

Yup definitely need to put that clutch in. AFR is unknown still, have the wideband but still deciding on header/dp combo. I don't want to weld the bung in the stock one then have to get a new bung and weld it again. I'm lazy in that regard, plus not having the time lately to do much of anything. I'm gonna go get the codes now.
