I've been searching for days on forums and have found many helpful ideas but nothing is working.. Even my auto tech teachers advice didn't work

B16a-from a teg xsi...... Swapped into an 89 civic wagon.....Engine is sputtering when I try to just cruise along and accelerate ... Goes away when more throttle is applied (doesn't have to be WOT)....map sensor , plugs wires rotor and cap all replaced .. Doesn't appear to be injectors or fuel pump ..
evap/carbon canister/solenoid isn't connected..... Also I'm getting no cel

I unplugged o2 sensor for cylinder 1-4 and it went away ... I plug it back in and unplugged o2 sensor cylinder 2-3 and it went away .. Comes back with both plugged in ... Help me please lol

 

could be an exhaust leak ahead of the sensors is freaking them out.

 

The manifold and gasket appear to be intact ..
Vtec works fine and wiring is done correct I double checked

 

I would check your throttle position sensor if you haven't already. If it tests good you may try adjusting it. I'm working on an mpfi swap on my d15 and having a similar issue to yours. I was able to improve on it by adjusting the tps so the voltage is about .7 at closed throttle. Not correct, but it has helped my driveability while I work on isolating my issue. I'm going to grab another sensor as well as I believe mine may have a bad spot.
