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!
