ok...so i put a str/bdl fuel rail on project b18b just now...used everything stock that came off the oem rail...and now the car idles at like 500 rpms...then jumps up to 1000...then goes back down whats wrong with it?

 

Is that the only thing you changed? Start off by double checking your work make sure you didnt forget something that would cause a vac leak. Then id move too the IACV and FITV. after that just load the shotgun up

 

everything is hooked up right...no vac. leaks...i dunno where the iacv is on a b18b...i'll check the fitv tomorrow...

 

fpr line

all iacv's are the big sensors on the back of the manifold

 

my fpr line is fine...i checked it...i check for leaks and eveything...i did it the same way donald told me to. i didn't mess with the iacv, how would it get messed up?

 

i dont know cursed hands. Honestley dont know how you got a vacuum leak from replacing a fuel rail but i guess back track your the one who did the work

 

i guess i'll check it tomorrow...i'm going to bed...

 

oh wait...you have to change the fuel feed fitting to the other side of the rail...stock its on the passanger side...i need to change it over to the driver side and put the plug on the passengers side. werd :1

 

if the injectors are out while ur doing the rail, make sure the big-O-rings sits in the bottom of the injector is sealing correctly. or else air leaks directly into the manifold. Also rest the ECU

 

so it has nothing to do with the fuel feed line being on a certain side?
