A strong odor of exhaust inside a car while idling or using the heater often indicates a leak in the exhaust system, allowing harmful fumes to enter the cabin. This can occur due to damaged gaskets, cracked exhaust pipes, or issues with the heater core, which may allow exhaust gases to mix with the vehicle's heating system. It's crucial to address this issue promptly, as inhaling exhaust fumes can be dangerous to health. Regular maintenance and inspections can help prevent such problems.

Why does your 1994 chev c1500 with a 5.7Lt smell of a strong gas odor at exhaust when idling?

How is it running? Is the mileage ok? Have you checked the computer diagnostic codes? It's possible that the ignition isn't doing well and you're getting unburned hydrocarbons out the exhaust. It's possible that the oxygen sensor is bad and that the engine is getting too much fuel in an effort to compensate. It's possible that there is a problem with the EGR valve or even the catalytic converter.
