Dear Tom,
I own a ‘97 Buick LeSabre with a 3.8 engine. When I remove the gas cap to put in gas, there is a release of fumes from the spout from the buildup of pressure. What would cause this pressure?

George,
There is a problem with the way the gas tank is purging pressure. Pressure inside the gas tank is released through a vent on the top of the tank. There could be a problem with the vent, a blocked purge hose, or a plugged vapor canister in the EVAP system. The system needs to be checked out. Best to you.

Possible Causes of a Dead Battery

Dear Tom,
I own a 2004 Cadillac Escalade. The battery light comes on for one or two minutes, then it cuts off and the dash says ‘battery not charging.’ What does this mean? Also, sometimes when I don’t lock the car at night, the car will not start the next morning and I have to get the battery jumped. What’s going on?

Dear Tom,
I own a ‘02 Toyota Highlander 4 cylinder, 62,000 miles. My local shop sent me a notice to have the EFI throttle body serviced. What is an EFI throttle body and how often does it need service? The vehicle is running fine, so I wonder if this service is really necessary at this time?

Engines Often Use Oil During Break-in Period

Dear Tom,
I bought a new 2010 Audi A4 in August of last year. Two months and 1600 miles later the oil light went on and the oil level was at the minimum line on the dipstick. It required a quart of oil. When I called the Audi service at the dealership they said that’s normal and that the Audi engine burns oil to the tune of about a quart every 2,000 miles. Is this true? I always thought having to put oil in meant leaking seals, gasket gone, or some other problem. What do you say?
