Replace the fuel filter, give it a tune up.
The loud screech is probably your belt, replace it.
And, I have not heard very good things about Maaco.

lol... (with you as I feel your pain). Anyway, fuel filter, air filter, check all vacuum lines.

Be careful your not overfilling it when you gas up. Does theleak stop after a while? (I mean before the tank is empty).

Check the belt as K says but check your clutch bearing too.

Maaco's OK if you don't mind your tires and trim painted to match.
