So I been have idle problems with my b20v and it Would throw a code 43?? Was wondering could this code be causing my idle problems?and I do have a wideband but It would stay stuck at 10.00.could it be from my wideband sensor being blown? Or something else

 

Honda error code 43 relates to fuel pressure regulator issue – You should also check for vacuum leaks.

Kev

 

I'll check my fpr.im also missing the washers that go around my injectors would that cause a leak?

 

Also once that code would come on.i can turn off the car and it's gone..it only comes on once in a while if the car is not fully warmed up

 

bro...you need to fix the issue...

 

what do you mean?thats what im trying to figure out.i don't know what's causing it
