my car is a 90 accord ex.
after driving on the higway for 10 min it will give me a check engine light. only if its driven at highway.
i got the code and it says code 43.

code 43 is "fuel delivery system"
now how the hell do i fix this?
i don't even know where to begin.
any ideas.

 

fuel delivery....i would check....fuel pump.....maybe try changing the fuel filter....start there....or try doing a search....it's the red highlighted one on the top right of this page.
goodluck

 

ok code 43 is either, 02, fuel pressure regulator, or main realy. id try 02 first then realy
