hey i need to know which way i turn the nut to make it rich, thanks
help me my cars rujnning lean

 

how do you know that your car is running lean

did you have it hooked up to a wideband o2 sensor
and why not just use the stock FPR?

 

loosen will richen the mixture tighet will lean the mixture

 

im pretty sure you need to take vacuum hose off FPR to adjust proper Psi.

 

i tried adjustin the FPR to richen it up but it didnt make it any richer, what other reasons would it be runnig so lean for, it didnt use to run like that 2 weeks ago, now it stays at lean when i drive, adjsting the FPR doesnt help the leanness

 

does anyone know what else could be causing it to run so lean

 

what kind of fpr? do you have fuel pres gage?
i thinking weak pump or a restriction in the fuel supply line.

 

check your plugs. if they're fried lookin you're running lean. how do you know that it is running lean at cruise. do you have an a/f gauge. if so sometimes hondas run pretty lean at part throttle cruise for emmisions and gas mileage reasons. if it's running a nice and rich at wide open throttle then you're probably cool. and as far as I know tightening the fpr will raise pressure by cutting off the return line. i have an aem fpr and if i remember right, turning it to the right raises pressure. i mean, it only makes sense. you should invest in a gauge to put on your rail that way you can see how it's changing while your car is on.
