Hay there,
I want to know is the EGR vacuum port supposed to leak down or hold vacuum? mine leaks down to 5psi fast then slowly to 0?? is it supposed to do that??
I am having a horrible time chasing a vacuum leak that flips my a/c dash vents. I have replaced all the vacuum lines i can touch. Seam sealed my vacuum canister, replaced a leaking iwe actuator on pass side, all the pcv elbows replaced, replaced the intake manifold gaskets and also water tested the intake manifold & not a drop..& i haven't found any new leaks. but i still have a p0171 and p0174 lean banks code and my dash vents still flip under load going up a hill. i just replaced a bad fuel pump when the code came on but i pulled and plugged the evap line and the dash vents still flip. its driving me crazy any help or advice
PS i plugged the EGR vac line & it still flips the a/c vents
