first let me tell you guys what i've done to the car, cause that might be causing the problem

i have a 2000 Si with CTR cams, CTR ECU, ITR Valve Springs/Retainers, ITR intake Manifold, ITR Fuel Rail, ITR CAI, JDM ITR 4-1 Header, 2.5 in/out carsound cat. B & M FPR set to 40PSI with vaccum hose off.

now here's the problem

everytime i start the car it will try to die(drop down to 300-100 rpms) i try and press the gas pedal to bring it back up, but it's like the cable isn't even there.

recently my cat broke and is rattling. when i am driving the car runs perfectly. i can take it up to 9100 rpms as indication by the ITR cluster that i put in.

i don't want to start putting the old engine parts back in unless i have to.

someone please help me

 

anyone?

i'm thinking too much fuel

would i be able to fix this with a VAFC?

 

Have you tryed playing with the fuel pressure yet? If you have, the first thing I would do is swap a stock FPR on it. For some reason I have seen numerous Hondas run shitty from the B & M.

 

i never had a problem with the B & M, it's been on the car for year,and it didn't cause any problems, i'll try and see if i change it tonight if it fixes anything
