Q: Car stalling; gas smell

asked by on

My car is stalling, and I smell gas.

Hello. If you smell gas and it is stalling then you either have an internal or external fuel leak. If there is not any fuel hitting the ground and the smell is coming from the exhaust, then you either have a bad pressure regulator or a bad fuel injector that is stuck open. If there is a leaking fuel line, then this can cause a fuel pressure drop, which can also induce these symptoms. I typically check the fuel pressure first with a pressure gauge to try and determine the problem. If you are going to have this done, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose your stalling issue, locate any gas leaks, and make the necessary repairs for your car.
