OK so ive had my integra for awhile now, before i got it it had a motor rebuild etc, i was told the motor is out of a 95 teg and it has a 95 ecu, the motor is all stock except for 12.5 to1 compression pistions, i have an apexi afc on it to control the fuel.
now the issue is when i am cruising on the highway at a constant speed it acts like its over loading with fuel or something and starts sputtering really bad until i give it more throttle then its fine

any ideas?????

No mine does the same thing except only at like low rpms when I first start it. I think I need to change my fuel filter on the firewall.

i think mine may be something stupid like the o2 sensor, ill find out in a couple days when i finish redoing the whole exhaust i guess
