I was told by a long time GM dealer mechanic that it is the gas cap. It is losing its seal, allowing the fumes to come out the breathers, one of which is located in the engine compartment, one under the vehicle by the gas tank. He said an aftermarket cap won't work, only an EOM replacement. But the price! Calling a junk yard for this one!
