I have a 1993 Honda Del Sol Si 1.6 VTEC. I am reading a CEL with a 43 Code, being a fuel supply system. I'm reading that it's most likely an O2 sensor. It would make sense that it would be since I am missing my secondary with no wires to be found to put a new O2 in. It's a stock 1.6 so there wasn't a swamp. However, I am getting really bad fuel economy and the car isn't as fast as it should be. Timing is about perfect. Im thinking it could be possible injectors or fuel filter or something. I need help. Being the wire is for the second O2 is missing, would my CEL still be on?

 

Bump?

 

There is no 2nd sensor on that generation. Try again.
