Question about 2003 Cadillac CTS

1 Answer

Fuel leak, strong gas smell inside and outside of car

I have a 2003 cadillac cts, and when you drive you can smell gas. The smell is worse when the car is in park and running or at idle at stop lights. I cannot see any wets spots or drips but it is now so bad inside that my clothes smell of gas after driving the car.

    Look at the back of the manifold, move the rubber hoses out of the way, and you will find a black plastic screw cap. Tighten this screw down. This will cure the smell.

When you look for a fuel leak, make sure the engine is running. the fuel lines will be pressurized and you are more likely to spot the leak. if you see fuel squirting, be careful since it under a lot of pressure. it might look like a single strand of a spider web. also, you should wear eye protection since gas in the eye would be a bad thing. needless to say, don't light a match or lighter for light to find the fuel leak. since gas is explosive, you probably should take it to a shop if you can't fix it. it could be dangerous if gas drips on a hot part. fuel vapors are explosive too.

You have a rich fuel mixture that ruined the exhaust converter

Google the PO430 code

The smell may be a coolant leak on the exhaust

2003 cts smells like its on fire


I had the same problem. The dealership said it was a dirty cabin air filter. An ace mechanic diagnosed it as a very small oil leak from the valve cover gasket heating up as it ran down the side of the engine. We replaced the gasket and the intermittent burning smell disappeared.
