I recently just pick up a 95 Honda Accord with H22a swap. Im having this troubleshooting with a CEl code 43. Its Fuel Supply System, I have looked it up and some people said it might be the 02 sensor(which I already put a new one on) Resister Box ( Already put a a new one on also). Plus to add another thing the car keeps cutting out a 5800 rpms. When it gets up to 5800 rpm it just sounds like a rev limiter, now you and I know a stock h22a dosent redlined at 5800 rpms. Really need help, and check engine light will be off when I first start driving. Bout like 5 min down the road it will pop up. If you can I need all the help I can find, Thanks

It's gotta be something along that circuit. It will not always be the load; its something else in the circuit. Trace it back.

Circuit as in the 02 sensor??

The wiring of that 02 sensor.

Whenever there's a CEL for the 02, EGR, TPS, MAP, etc doesn't mean its the sensor itself. The CEL comes on to tell you that the wiring circuit isn't operating right.

So further diagnoses needed.

I will check on that in the morning man. It will probably be best to put a multimeter on it and check it make sure its even getting powered.
