1985 Chevy Caprice V8 Two Wheel Drive Automatic 22ish miles

Hi um I just got my radiator gasket replaced on my car and soon after it was stalling iratically as I stop at a garage to hav it checked it stalled and I couldn't get it into the driveway it was also pouring out I only say this because the mechanic said was the cause he then proceeded to change the idle setting on the engine when I got home the problem was not fixed it's been stalling irratically still. Anyway now it seems As though the stalling has been fixed and now when I accelerate the engines pitch is just way off it doesn't sound like it's breaking it just sounds off is that just the idle change or something more serious?
