Right now my car is getting about 17-18 mpg. It is an obd2 b18b1 in an 94 civic ex, with an obd1 p75. Whereas before I had an ls vtec (b18a1 with 99 gsr head the head was obd2) getting around 24 mpg on an obd1 p28. After the swap it's like the gas mileage dropped was swapped as well.

I do not know what is causing this problem, at first I was thinking that the evap system was causing this problem since one line is not connected to the engine (Due to me not knowing where it goes. The same line I plugged with a screw.).

Yeah that is way low I get a solid 30mpg in my EK Ls swap. Clean your TB and injectors. If you have not had a tune up done in a while then get that done to plugs, wires, cap, rotor and fuel filter.

Do you have a engine light on? If you do check it also. Tune up would help.
