i have a 1991 honda civic dx d15b2 dpfi.. it starts, runs, and idles fine! when i take off in gear and step on the throttle the car bogs and sputters! it only does it at about 3.5 to 4k rpms?!?! i replaced my fuel injectors because i had code 16 on the ecu and after i installed them the code still blinks 16 times?! do i need to reset the ecu? i also replaced the fuel pump, fuel filter, spark plugs, timing belt, water pump, both injectos, cleaned the iacv, and fresh oil change and oil filter. i also replaced the cat with a straight pipe. i replaced all these parts within the last week and still didnt solve my problem! any help appreciated

 

will this car rev up in neautral or just dies when in gear?

 

check your timing (mechanical and ignition)

 

Check your spark. Had this problem on my B swap...problem stopped after I replaced the dizzy

 

the car drives fine when i stay under 4k rpms. its when i step on it that it bogs and sputters but the car still stays running. it doesnt ever die. the timing is good and i got spark on all the plugs. any other suggestions. still havent solved my problem.....
