So I was driving home from work today and my car bogged really bad while driving, and went away after about a minute. I look down to notice a CEL. When I made it home I pulled the code and it was a 43, fuel supply system. I was wondering if there are any common problems found with this code?

BTW: Cars is a 94 Civic lx 4d with a d15b7. Thanks in advance.

 

My guess is fuel pump, or filter.

 

I will keep that in mind. But the fuel filter isn't that old. I started it up about 20 minutes ago and the cel wasn't present anymore. Is this normal?

 

Well, i have never had the problem myself. What does the vacuum line that goes to the return side of your fuel rail look like? I would start with the simple things.

 

They all look good, don't know how old they are. But I have replacement vacuum hoses that are ready to be installed. Thanks for your help.

 

Ok so after driving the car all day today. The CEL came on again, same code. But about after 5 seconds it did a single blink and repeated the whole process. So now I am confused. Do I have a code 1 now?
