i've searched and searched and nothing helped...

I have a b20b swap into a 94 civic coupe. ive had the swap done for a bout 2 months, well the car runs fine except it sputters when i let off of the gas and give it 3/4's throttle. i changed the spark plugs and wires and still no help. also i check my codes and it gave me the tps sensor and a o2 sensor. ive been told that if the tps sensor is bad it will throw off the o2 cell code. i changed the tps sensor and it made it run worse. i have had no help, i have searched, any help would be great.

 

sorry that i couldnt be of help but i just got a B20B too, and i was wondering can i get your list of all the stuff you did to make it fit in the 94 civic?
