New info
Replaced Isoloar bolts and gaskets but the "sniff" sound I hear when I hit the throttle is still there. Do those vacuum regulators fail and cause the 02 sensor codes too? There seems to be 2 of the vac regulators back there. One on the back left of the engine and one against the firewall. I had the thing fired up without the cowl on it and am 90% sure its that back regulator that is making the sniff. Obviously the 02 sensor codes are gone for now, and I don;t know if that fixed it yet, but is that sound normal? All the vac lines back there are snug, the new bolts and 6 plenum gaskets were done so I know it's not those leaking air. Just wondering if anyone has heard this mystery sniff and knows if it is something different...
Thanks!
