Hey guys,

I put a Y8 intake manifold on my Y7. The car is a 2000 Civic CX and the manifold is from a 98 Civic Si Auto trans so it isn't air injected. I hooked the very top vacuum line to the PCV valve, the rear one to the brake booster and their is a small port that I plugged. I did not cross the TPS or MAP plugs. I ran the lower front line to my black sensor that I have no idea what it is which goes from there to my evap purge cannister. I ran the coolant line from middle of the tube on the back of the block to my IAC valve closest port and the other one goes back into the flange where the bottom rad hose runs to. Now If I unplug my MAP sensor the car idles around 1000 RPM and floods and hesitates. If I leave the MAP sensor plugged in I have no CEL and the car idles around 2500-3000 RPM and sometimes fluctuates but still floods out. I am running the Y8 injectors. I tried the Y7 injectors but it still flooded out and didn't work properly. I tried the MAP and TPS from my Y7 throttle body and still no change. I hope you guys can help me I need my car working properly ASAP.

Thanks in advance!

check your FPR? did you plug the vacuum line into it? what did you do with the hose that it plugs into? Where is its drain hose? do you ahve a FP Gauge if so what is your Fuel Pressure?
