Went in for smog today. Everything passed but the gas cap, EGR functional test & timing (was at 11). Luckily everything else including the sniffer test passed.
They said the EGR has no vacuum.
Would this be a result of a bad VSV? Bad EGR? Vacuum modulator?
Thanks in advance!
P.S. I did the head gasket awhile back and replaced all the vacuum tubes then, so those should be good.
