Rebuilt the engine in my 92 Accord and now when you plug up every sensor to the ECU it shutters going down the road at speed. But if you go WOT it goes away or if you unplug a sensor(like throttle angle sensor) it goes away but the check engine light stays on. I know its something that the computer is controlling but I cant figure out what it is. It throws a 43 code I think when everything is plugged up.
Anyone with some Ideas of what may be going on?

 

Code 43 is typically an O2 sensor issue.

Check the O2 sensor, wiring, or connectors for possible damage during hookup or forgot to connect.

good luck
