well i had an exedy twin installed about 600 miles ago.. like 2 or 3 weeks ago. and a week before that i installed new NGK bpr7es plugs. my car runs on e85 as well.

today i rev up to around 6k for the first time since the clutch was installed and i get a stutter like spark blow out, but i just installed new plugs and gapped to about .02? so i dont get it..
could it possibly be becuase the car wasnt 100% warm? but the problem with this theory is i went to the mall and parked the car for 2 hours at most and when i left it did it stuttered again.. and the thermostat needled was 1/3 the way up fron C

it seems to only do this when its not 100% warm ( themostat pointing to the center between H and C)

but its never done this before. which leads me to point to my new exhaust? i used to have a vishnu exahust and i changed to HKS and the HKS seemed to have fewer bends in it? could that be the problem?

thanks

I checked my plugs yesterday and this morning mine did the same thing. I THINK I did not put back in a plug wire properly, I checked and it seemed that one was a little loose, will drive the car later and see if that was the problem, because it never did that before.
Maybe you can do the same.

With that power level, shouldn't you have BPR8ES plugs? I think 7's aren't up to the task with that power.
