This may be due to your ECU needing retuning. Check on that first.Garyc17 said:Anyone can help me... I can't seem to locate the plunger (FITV) valve. I have a P73 Type R Manifold and it only has a IACV. And the IACV hole is located behind the throttle body flap in the plenum. I checked the IACV and the filter seems clean. There is a hose that goes to this part under the throttle body put it does not have the plate as mentioned by cautela dude?
