Hello, I have a 98 accord ex sedan (manual) that I recently swapped an h22a into. I rebuilt everything to stock specs and the internals are almost completely stock. The only difference was that I installed a set of pistons to bump the compression up to 11:1. I have followed the h22 swap thread that drift made almost to the letter. I even took the harness out and chased every wire.

Now here is my problem, the car runs very rich. I have installed an adjustable FPR and set it to stock specs and nothing has changed. The car reeks of fuel when running and it sounds cammed for some reason. I've tried everything I could think of, from stock injectors to all new ignition parts. I am running a 37820-p13-n50 ecu. Does anyone have any suggestions? Any help would be greatly appreciated.

 

depending on which injectors you are running is what determines if you need a resistor box

low impedance needs a resistor box while high impedance needs no resistor box

an exhaust leak will cause you to run rich too as it will see the outside unmetered oxygen in the air leaking into the exhaust as needing to bump up the fuel

 

I wired a set of resistors to make by own resistor box, since they are obd1 injectors. My next step is the exhaust, so I need to try to see if that helps anything. Thank you.
