You are burning oil, causing the blue smoke. It is mainly cause by worn piston rings. Also will coat your spark plugs with oily residue. Try an oil additive such as "stop smoke" or another such brand to reduce burning your oil and it may recondition your seal sand stop it all together.

Some of these engines have a place to drain water out of the fuel system.. Some fords actually have a stick under the hood that you push or pull That opens a valve on a water collection bowl. It's not labeled usually. It might state where it is in the owners manual under fuel water drainage or something similar.. if that bowl is full it will cause hesitation... If it gets over full it will cause runability problems. Another possibility since you said it's black smoke is one of your injectors is sticking at low rpms and squirting raw fuel into the cylinder till the rpms get up enough to burn that fuel off completely then then the injector works a little better.... Do you notice any missing... Feel something under the hood like the air cleaner housing and make sure the vibration is constant and doesn't have a small sudden shake and the n smoothe... And then a small sudden shake again.
If it does have this shake you can trouble shoot which injectors by with the engine running loosening an injector line and seeing if the engine runs worse or not.. If it runs worse tighten it up and move to the next line till you unscrew one and feel and hear no difference... When you find that one that's the injector with the problem.

White smoke is indicative of a leaking head gasket or cracked head.
The liquid enters the combustion chamber and is ignited with the gas - and the exhaust is water vapors.
(unless you drove through a puddle that splashed watyer onto the exhaust)
The head gasket/cracked head is most evident on startup.
If your coolant level goes down with no visible leaks - your problem is internal (head gasket failure or cracked cylinder head).

the puff of smoke is one of 2 things, dampness in the exhuast from setting over night,like ice water on a hot day ,the glass draws miosture,this is harmless, the other is worn valve seals,a puff of gray blue smoke then it,s gone,harmless.,but if it smokes while your driving it after 2 minits you may need new positive check valve $5 part,if it uses excessive oil have it checked

Well, I think that the latest problem could be a symptom of a blown head gasket. The white smoke, can indicate that antifreeze is going into the cylinder, unfortunately. It would have a sweet smell.
Bad gas, is not a usual problem in the U.S., anymore.
But, if you think it is bad gas, then you could change out the fuel and add fresh fuel to see if the condition gets better.
I don't think it will, though, without service to the head gasket (possibly).
Check the spark plugs for signs of antifreeze contamination or fouling.
Good luck on this repair.
