Every time I idle my car there is smoke coming out on its exhaust and the smoke smells gas. What would be its problem?

What color is the smoke? Blue your burning oil, bad piston rings, valves. Black smoke excessive gas running through engine. White smoke cooling system problem.

It sounds like you have a fuel pressure regulator that is leaking, can you remove the vacuum line to see if there is fuel present?

Let me know what you find

Best, Ken
