Welcome to the forum
I would try pulling the plugs when it is cold. Make sure there is no antifreeze on them. A small head gasket leak can do this.
Does it start any better if you hold the gas down a little bit?

Or the all-to-common intake gasket leak.

How has your coolant level been? Disappearing, perhaps?
