yesterday i did a full tune up on my car to pass my emissions (previously failed) plugs,wires,cap,button,air filter,fuel filter,pcv valve,and oil car started shutting off on me when i would stop at red lights or after i had been driving the engine would just drop to 0 rpms and either slowly go back up or just die. I figured it had to be a vaccum line issue so i was checking it and i unplugged the...

off the top of my head im not sure at the moment. the fuel pressure is running at max psi ...
your car is running lean and is why you failed. w/ the fpr connected @ idle the vacuum pulls the fuel pressure down. @ atmospheric (line disconnected and wot) the fuel pressure is high. if it's a stock regulator then it's probably between 45-48psi @ atmospheric. if disconnecting caused the car to run better @ idle the fuel pressure is as if it's @ wot, but running the injectors per the fuel ...
doesnt need to be tuned...
You have a stock car
plug it all back in and adjust the throttle screw on the tb not the one on the cable part, but the flat head right in the center above the air tube.... and you srew it out lefty loosie and your golden... also a good throttle clean would be nice while your there...

FPR going bad in a Honda/Acura is rare
ok thanks alot ill let you know after i hook everything back up and adjust the screw how it goes
Ok so heres the update i messed with it on my lunch break reconnected the hose from the fpr to the manifold and upon examining the screw on the tb oit was closed completely (screwd all the way to the right) i loosened it up by screwwing it to the left it made the idle stronger but i havent driven it yet ill let yall know when i drive how it goes

Quote: Originally Posted by STRteg It didnt fail it passed emissions great,it had failed previously because of a bad cat and in need of a tune up and its all stock just as tech 5 said,thank you for your input and knowledge it failed previously and didn't pass until you disconnected the fpr vacuum line. i bet even after changing the cat and tuneup if the fpr was connected it wouldn't have passed b/c running too lean and throwing off...
