I got a 95 civic coupe with a d16z6 in it. Everything pretty much stock. It doesn't sputter goin normal but when I step on the gas it only sputters from 5k rpm to 6.5krpm. Weird problem I don't knw. I floor it and it doesn't sputter in first or second but when in third, it will sputter trying to get past 5K. I don't knw the problem it. Any help, thanks.
