95 ls integra with 94 gsr b18c1. Im having a bunch of problems with this engine. Its throwing the code 43 for fuel system supply. It gets terrible gas mileage and the only way it will run is when the timing is advanced all the way. Anyone who can shed some light on this issue would be great. thanks

 

If the only way it will run is with the Ignition timing all the way advanced then maybe your Cam timing isn;t correct. I would solve the running issue then deal with code 43. Did you just perform the swap? What other problems are you having?

 

Ok i got the code 43 to go away. It was a bad connection on the IACV. I performed the swap about a month ago. The advanced timing problem is all im having.
