hey guys my cars runnin rich......i was wonderin.......i have a 89 cvic DX with the d15b2 and the peice of **** dpfi......where is the fuel pressure regulator and can i adjust it......does this car even have one????????i was hopein i could just adjust it and that would fix my problems but i need your help once again!

 

it shoutld be on your fuel rail,it the thing with the white cap,im 99% sure its not adjustable. ive never had a need to screw with it.but im assuming since a lot of people go out and specifically buy adjustable ones i doubt the stock fpr is.

 

The stock regulator is not adjustable. If the car is running rich try giving the car a tuneup.

Cap and rotor
New plugs and plug wires
New O2 sensor

 

i just gave it a tune up.......and some jack *** for a mechanic here told me it was my purge soilenoid
what is that and where is it? where would thge regulator be on my car?

 

fuel rail,it has a milky white cap.

 

if he has dpfi he has no fpr or white cap
people need to read better
my dpfi was running real rich nothing i could figure out changed it
i am in middle of a mpfi swap and wow its way diferant already more throtle response and no more rich fumes

 

i read just fine thank you,i just assumed it would be the same for a d as it would a b16.
