ok heres the problem i have a 91 integra with a 99 si b16a2 ,im running in obd2 .When i connect the hose from my fuel pressure regulator to the intake manifold my car jus dies out but when i take it off ,the car idles fine.ive also noticed i get horrible gas milaege, another side note when i hold the throttle steaddy between 1500-3000 the rpm needle bounces all over the place. i cant seem to figure out what is causing this ,anyone ever had a smiliar problem ?

i have a obdo>obd2 conversion harness on it that i got off jkobd.com,everthing is fine exept that .its got me serious stumped.i thought it might be the map sensor .so i extended the wires to the one on the throttlebody and still the samething.

You need to get all of your vacuum lines correct, fix these and you will get good gas mileage, find a diagram and start from scratch, thats what i did and it fixed the same problem.
 
it should increase the idle speed;not die....

try changing out the FPR for another one
make sure o ring is good between regulator and rail

is it a stock reguator?
 
i changed the regulator and still does the same thing,would being in obd2 casuse my car to do this i am about to run obd1 in my car anyways. Do u think this will fix the problem . o yea by the way im throwing like 6 codes
