tried to run a p28 with the 2 wire iacv and the ecu is messed up so i switch it back to a 3 wire iacv and use the y7 trottle body and y8 rotor and start the car and get a horrible idle from 1k-3k.

in all i think the map and tps are mixed up. can someone lmk the sensor wire colors on each.

is it possible to have the iacv hoses backwards?

this is on a DX 99 civic. using p2e ecu for now till i fix the p28.
