Okay I Have 94 Civic Sedan Dx I recently swapped a D15B7 Motor in motors runs great low mileage and awesome pull I just have a problem I recently replaced a lot other than engine I have done rotor button ,distributor cap, wires, plugs ,alternator, new terminal wires on both terminals of battery , so I goto take off in the am or whenever I first start car after a while and I get a bog through every gear the car fights it but it still bogs in low rpms it's like it's not getting the fuel pressure it needs if I dump the gas it Bogs worse I also did fuel filter only thing left is fuel pump I'm kinda stuck because many Honda mechanics and friends that have lot of knowledge in Honda civics my year and everything can't figure it out and usually leave scratching there head I'm thinking maybe fuel rails or fuel pump but I don't wanna keep wasting money the motor was a carburetor motor from Japan I blocked the carberetor off with a restricted plate I just don't know what's causing my fuel pressure problem any help would be greatly appreciated as I'm new to Hondas
