I finally detected a small spot on the parking deck. After giving it the "sniff" test I took it ti the dealer. They put it on a lift and found evidenc of a leak in the No.1 tank.

From that point on it became a major undertaking. The only way to inspect the tank is to:
Remove the rear wheels
Remove the axles
Remove the transmission and differential
Remove the mufflers and tailpipes
Remove the gas tank
A leak was found at the top of the tank where a hose is attached to connect to the other tank. The solution was to replace the tank. I got the car back yesterday and everything is OK. GM said they had not had this
Hi alk,alk3997 said:Just had the same thing happen to my '04. Two days after its return to me the check engine light just came on. Based on the other posts (what a wonderful forum) I'll bet the oxygen sensor is bad.
Looks like a leaky #1 gas tank is a (relatively) common problem.

Absolutely my experience too Bob.standby said::iagree Not only that, but genrerally I found out in the beginning that you could only get about a tea cup more gas in it by squeezing in more, not worth the smell or the over pour.

Eight hours of labor for the gas tank replacement. The crack was visible I was told. Add a few more hours for the (apparent) O2 sensor replacement.upstate said:Wow that has to cost GM $2,000 each repair. I'm glad I will never have this car outside of warrenty.
