swapped my 00 ek from y7 to a y8 with 00 ex wire harness with a p28 everything runs fine except the idling. when i come to a stop the rpm would drop to 200-400 and few times the car would die on me because of the low rpm. i've tried to adjust the idle control screw thing, cleaned the idle speed sensor,hoses, throttle body with berryman b12 cleaner, but made no difference still idles low. then i switched back ecu to the p2p and the idle was fine and running good only difference was that the engine check light was on because im running 1 o2 sensor. anyone know how i can fix the rpm with the p28 ecu?
