B16a bucks when i drive it

With a 1990 automatic integra ecu my car runs fine as soon as i hook up the obdo B16a ecu my car will buck when it moves and when it isnt moving and i hold it at like 3 grand it dies down and then fires back up. I put the integra ecu back in and it runs fine. could it be from the ecu because i have and obd1 motor ini the car will i need and obd1 ecu and jumper harness. Whats my problem with the bucking.

which distributor and injectors are you using?

Well since the teg ECU is OBD0 you can rule that out... Its gotta be something that B16 ECU... Is your car an auto? And what numbers does the B16 ECU have on it? Theres 2 different kinds that come with those PW0 and PR3s (I think), and then theres auto and 5 speed...

yea, we need more info whether ur cars stick or auto etc etc
