If the engine is cold when doing a compression check, your readings will be way off, much too low. It sounds like your engine is running much too rich, which also contributes to gasoline washing the cylinder walls/rings and that can also lead to low compression.

Check all of your vacuum hoses first. Replace any that are split or appear to be cracked. Remove the cover over the throttle body and inspect the hose from the idle air control to the top of the black vacuum tree. Make sure none of the nipples are uncovered, missing.

Never put ATF in the gas tank! One bottle of dry gas is enough to collect any water and send it to the injectors within the first 5 minutes of running. Remember, the pickup is at the bottom of the tank so that water will be sucked up first.
