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.

 

bump

 

what kinda plugs you put in?

 

Do you know if it is running lean or rich?

has this problem just came up or has it been like that since you got the swap?

 

"has this problem just came up or has it been like that since you got the swap? "

yes it has

 

what ecu are you using

 

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 had the same problem turned out i had a bad injector

 

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!

yup

 

if the car is bogging, its the distributer i had this problem on my 2000 si, check the coil

 

I have the same problem, but only at slight throttle, and after idling at a stoplight

 

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.
