I have a jdm gsr swap in my civic, recently my car has had some acceleration problems. When the motor in cold it starts fine, as it warms up it starts to stumble. Only when you gas it moderatly fast it stumble and boggs down, as you let up on the gas it decelerates as normal. Like the motor is starving for fuel or something, i have done numerous tests on it and have came up with nothing. any advice would be greatly appreciated. It has stumped even a honda guru i work with. I have changed sparkplugs, fuel filter, changed map sensor, coil, fuel pump, tested for vacumm leaks, and other tests. drop me a line if you can help thanks
