to get rid of the wheezing boost the temps to about 95F for a day or two and he will get rid of that no problem happened to a snake i rescued and the problem went away the next day after that i regulated the temps back to normal and he has been fine ever since, also look for wrinkles or wrinkly skin in the snakes body thats a sure sign the snake is dehydrated, good luck with him keep us posted and your a great person for rescuing him!
