i have a 94 hatch with a jdm d15b swap in it. Car runs fine until its warmed up. When warmed up it boogs and hesitates really bad below 3500 rpm easpecially when at wot. Right after 3500 rpm it takes off like a rocket wtf. We changed the plugs, fuel filter, checked all of the sesors.(there was no codes). Were thinking it might be the o2 sensor or the injectors. Any other suggestions would help thanks.

I have the same problem currently... It occured awhile back and found that its a mis-fire under wot. I changed the plugs and the problem was fixed but now its back again. Im going to check my cap and rotor next.

From what i have found its a definite misfire, it doesnt do it untill the car is warmed up right?

i just found out what was wrong with my car. i had a diagnostic done, and it was my "o2 sensor." the one before the cat. good luck!

Change your plugs. Make sure you use NGK's.

did you wash the engine bay recently? if you did then there maybe water in he spark plug hole. good luck.
