H22a4 to H22a question and misfiring issue
I have a 2000 prelude base, had the usdm h22a4 in it but was burning oil so I bought a jdm h22a black top and swapped it in. Do I need to change the ECU? Also since the swap it has been misfiring while I'm driving at lower rpms.. Changed spark plugs and wires.. Any ideas please?!
