Sounds like a Vaccum Leak somewhere. The engine's rpm's shooting up and down and sounding like its almost stalling is the prime suspect of it. I'd suggest checking your vacuum hoses going into your intake and see if any hoses are leaking or cracked.
I have the same problem let me know if you figure it out mine is a 89. But the same issue all the way down to the oil in the valve stem.
