hey guys gave my car a little service putting through new oil, filter, air filter ,gearbox oil and cleaned the maf and throttle body
now i seen this butterfly flap thing inside the airbox but it seems to be permanently raised when car is off and doesnt move when the car is revved up...
the car still hits a kind of v tec when it hits 5k revs tho. how do you keep the flap open permanently?
