HVAC problem....
I was messin with the y-pipe under the car and he had the intake manifold ripped off to do the knock sensors on the top of the car
and after that the HVAC will only blow through the floor and defroster vents, and the AC blows out hot air and it always smells like exhaust fumes...but I do have a small exhaust leak...anyone have ANY idea???
thanks ahead of time.
