i have a 95 honda accord lx, came with a f22b2 which ended up going bad. Also at the time i didnt know much about cars and brought it to some random mechanic to swap the motor and he completely screwed me over. By over pricing me and not even doing a correct job but i cant do nothing about it, no paper work to back up my word what he told me. what he messed up on is he swapped a f22b1 obd2 motor into my 95 obd1 car, he didnt switch out any of the wiring or anythign just got it running for 2 weeks and i only payed him half since i didnt have all the money but two weeks later my car started have trouble. it was puttering and didnt wanna pull properly, my last resort right now is getting a wiring harness to match the motor and a ecu? is that what i should do? btw im 16
