i got a jdm engine in my car (2jz-gte) . it ran fine for about 6months but now i have what feels like a misfire when i get to high rpms in 4th gear and higher. i changed the plugs and fixed all the leaks i could find. any suggestions? thanks

by the way i have a t74 turbo with an afc set to about 14 psi

Oh my are you serious?? that is so funny.

I had a misfire the other day, I thought I was gonna have to do a curtsy flush, but I was able to work it out just in time. Hurt like a mother. Maybe I should eat more wheaties, what do you think. Kinda gives you gas though, bloating and farting, not really that much fun but it sure beats get plugged with a fudge dragon, having it extrapilated by forcepts at the hands of a blue nosed doctor makin a buck. Geeze what a place.

check for more boost and vac leaks
