I have a 98B18B motor in a 93 Civic, DX. The motor is running off of the B18B engine harness, B18B injectors and on the stock 93 ecu. I have the PR4 ecu but everytime I try to use it, it runs horrible and stalls out when given gas. But occassionally when it does run well it pulls a lot harder. What injectors should I use? If the injectors need to be swapped, so do the clips right? What is the correct computer? Oh and could someone say why to run each part and the reason other than 'just cuz'
