Sputtering, idling

My car issue began, Feb 3rd during a downpour early that morning, on my way to work. I drove through a large puddle in my 95 Honda Civic (manual) and immediately afterward my car began driving differently. I've gone to two mechanics, the first over sold me on a new battery and tinkered around my injectors but never changed them just claimed to have cleaned them. The second just diagnosed that I needed a new radiator which I replaced.
Symptoms: there is a slow turn over. At times it may take 5 seconds for the engine to completely get going. Kind of like it is hesitating to fully get moving
There is a low idle when the heat is on, above and below 1RPM, otherwise the engine idles at 1 to 2RPM.
There has been a faint scent of antifreeze but it goes away.
It is prone to shut off when it goes from still to 1st if the rpms are not high enough. (I usually rev up to 3RPM to be safe)
And on occasion it will sputter and sound like a go cart idling while driving but will drive normal a little while after depending on how long I've driven it.
