been throwing a code 43 CEL with a P75 ECU anyone have any ideas?

 

Pretty sure a 43 is running rich

 

any ideas why id be running rich with stock fuel system?

 

i've had that code before . . . . usually it is from running overly rich. The # one thing I found a while back on my old car was that my stock FPR was stuck closed.

Do you have any mods or is the car 100% stock?

 

I had an intermittent 43, it was my o2 sensor.

 

a person i know had one and it was his fit valve.

 

what code is the result of the gas cap not being on completely?

that is the most common fuel error ppl get. The gas cap doesn't get completely tightend which results in a cel. Make sure your gas cap is on at least 3 clicks. Might also need replacing, but I highly doubt it.

 

its not the gas cap but thank you lol .. the car is a 1933 civic with a jdm 94-95 ls b18b and i do seem to be killing alot of gas so maybe i am running rich and maybe it is the fpr ??? anymore ideas and thanks for your help so far !!

 

 

I dont know if this matters or not, but it may be a recall problem. I have a 96 rs and i know there was a recll on their emission stuff. I had to have my charcoal canister replaced. Just thought i would throw that out there.
