Fuel/Egg odor at idle

[Xdt]

Guys, when I start my car it’s very rich at idle and has a strong egg smell. The odor will make your eyes water, if that gives you an idea of how strong the odor.

The car is a 1990 124k miles, original exhaust, with the only mod being new injectors, new plugs, new pcv valves. The car runs strong in power mode, does not bog, however under acceleration someone informed me of a little puff of smoke and the smell of fuel as I passed. Also, there are no codes displayed. This has been verified with tech 1.

My apologies for the lack of details, however as of now this is what I know.
Any ideas of what to check?

Thank you
