Fuel System problem
OK, its a 95 Integra GSR running a stock ECU.
I just put in new 450 CC RC engineering injectors, AEM fuel regulator, AEM fuel Rail, and new fuel filter.
The aem Fuel rail has a pressure gauge and I adjusted the fuel regulator to put out about 50 PSI.
I primed the car about 3 times and than started it and it runs pretty hard. I only ran the car for about 1 minute. The motor throbs back and forth at idle and when i hit the gas pedal the car acts like it doesnt have enough fuel and little power. The car is not tuned or anything other than adjusting the AEM regulator. The car ran fine before any of these mods. Any suggestion??
Thanks alot!

Yeah your runing way to rich. I'm surprised you got it to idle with injectors that big. 310cc is about the limit fo a stock ecu with no piggy back fuel computer to trim fuel out.Also drop your fuel pressure down to about 38-42psi. Get a v-afc or sfc to trim the fuel out...

Re: Fuel System problem (David555)
i dont really know much about the rest of ur setup but it sounds like you have way to much fuel there. 50 psi at idle with 450 cc's? is ur tach needle going up and down constantly at idle?
