hey guys, i just got an apexi vafc and the installation was ok except for the pressure wires (white and yellow) when i hook those two wires up my car ( 96 gsr) idles funny. the car runs normally but it putts a little bit at idle. the wires i connected to is the 3rd wire from the top right and that threw a CEL right away, so i tried the 4th wire from the top right. that wire was better but caused the weird idle. the reason why i tried both wires is because i found two diagrams. one claming the pressure wire was the 3rd and one saying it was the 4th. do you guys think its the setting on the vafc, or am i just hooking the vafc wires to the wrong ecu wire? i have the yellow wire into the ecu and white to the engine. any help (diagrams) would be appreciated.

Thanks,
Jon
