2002 Malibu stalls while driving, doesn't over heat. But can start smelling gas fumes before it stalls. usually wait about 5 mins then restarts. in higher elevation runs fine but in lower elevatio


It sounds like the catalytic converter could possibly be almost completely plugged up not allowing the exhaust to leave the engine like it should. It just builds up in the cylinder head and when it gets too much in it built up and there's no where to go, it'll stall the engine. By letting it sit for a few minutes, it gives the exhaust time to find a way out and the car will restart.

I would have someone check under the front of car while engine was running. Maybe then a gas leak could be spotted. Did he check the charcoal canister-it's a gas vapor collector from the gas tank, and maybe located at front of car. If the canister is full and not working to purge the canister and send the collected fuel and vapors into the engine, it might be what you are smelling.

Smell of gas and whistling sound


Its all connected.
The computer uses a solenoid to vent the fumes from the tank when the engine is running.
The vapor canister holds the fumes until the vent valve is opened.
The computer tried to vent the tank and something went wrong.
It could be from the excessive heat or something with the venting system.
A mechanic would test the venting system.

Sounds like the clutch is worn or the throw out bearing. You will need to have both checked. As far as the gas fumes go, check your air filter to make sure it doesn't need to be changed, if your fuel injected check to make sure you don't have leaks around your injectors. Finally check the gas fume collector for damage or bad vaum lines.

Gas fumes inside and out side the car when it is hot outside


Try having the area that the hose was disconnected from steamed cleaned, or go to a car wash wash and spray the area. It might help, that is if you already haven't done so.
