In trying to solve the mystery gassy smell on my 2000 Eurovan, I came across a similar story in the archives from "Dave dave2napa@... <mailto:dave2napa@...>" which sounds almost identical to the problems with my 2000 EVC.
Is dave2napa still on the list?
Dave, if you are here, did you find the solution?

Hi All,
While driving to Yosemite this past weekend, I experienced a strong gas odor in the interior of our 2000 EVC. We were traveling uphill at low speeds (35 mph) at around 5,000 feet of elevation. The car was driving just fine except for the gas smell. The smell started just as we approached the entrance gate to the park, the ranger and I both noticed that the car also has a strange mechanical humming noise. I pulled over and could not locate a leak and when I started the car back up, the mechanical noise was gone. Here is the strange part, with the engine off, I placed my hand on the gas tank and it felt warm and the contents appeared to be moving around (boiling/bubbling?). The engine and tranny temperatures were normal (190 and 212). We decided to continue on with the windows rolled down and after we started to descend, the smell went away, but shortly thereafter, the check engine light c ame on and the gear selector indicator light went out. All the while the car drove normally, but we headed straight to the garage in Yosemite Valley (fun way to start the trip).
The garage in Yosemite valley pulled the following codes: P0740 (torque converter clutch circuit malfunction TDC) and P0134 (Oxygen Sensor 02 Circuit no activity detected). However they could find nothing wrong and the car ran perfectly the rest of the trip.
Back in Napa, my local shop discovered that we have a vacuum leak at the brake booster hose. They will replace that tomorrow and see if that helps.
Any thoughts?
Dave
