Anybody ever had their EGR valve blow the vacuum line off the bottom of the modulator?
I finally found that my mysterious exhaust leak was, in fact, coming from an unplugged vacuum line on the the modulator. There was a bunch of carbon build-up on the base of the modulator and around the hose nipple, which makes me think something's not right.
I was talking with CDan (thanks for all the help, by the way!) about it this morning and he thinks maybe the carbon plugged something up and the pressure of the exhaust coming from the EGR might have blown the hose off the modulator.
No CEL with the hose unplugged, so I figured I'll drive it for a few days and see if it throws any codes with the hose plugged back in. The engine seemed to rev up much more smoothly with the hose plugged in... gotta go see how it drives. I wonder if this has anything to do with my hard starting when warm issue?
Thanks for any input,
Steve
