Why is gas coming out of the tailpipe of your caprice classic?

Gas coming out of the tailpipe of your Caprice Classic could indicate a fuel system issue, such as a leaking fuel injector or a malfunctioning carburetor, allowing excess fuel to enter the combustion chamber and not burn completely. It could also suggest a problem with the engine's air-fuel mixture, leading to a rich condition. Additionally, it may be a sign of other engine problems, such as incomplete combustion or a failing engine component. It's important to have the vehicle inspected by a professional to diagnose and resolve the issue.
