2001 Lincoln LS fuel system issue w/ hard start

Thanks.

Just had all the plugs, etc. changed out due to misfires last month due to valve cover gasket leak. Was running on 5 cylinders.

As for the smell, I think it’s both. Smells like gasoline but also smoke comes out of exhaust from excess fuel, too.

I will pass on the rest of the info to my shop and see what they say. Thank you again.
