5.7 is idling pretty bad and smells like gas out of the exhaust. No check engine light and the last time I changed the plugs they smelled like gas. Any common problems with these or any suggestions on what to check out. Tia.

Check the spray pattern on the injectors and the fuel pressure regulator. There are very few ways for too much gas to get in there.
I kinda agree with that. There are a bunch of things that can cause the problem, but only a few ways for the excess fuel to get in the door. I was suggesting to check those doors first to see where it's coming from, then you can narrow the field to who is opening the door.Actually there are quite a few causes for excess fuel. See code 45 Rich exhaust indicated diagnostic aides Section 3 Page 68 in the Fuel and emissions Service manual
If it’s been sitting the gas could be bad and not burning.
Have you gotten it up to operating temp and driven it at highway speeds?
