My 86 fiero 2m4 keeps bogging out when downshifting, yes its an automatic. I have changed the idle air control valve and plugs and cleaned out the throttle body. Not sure where to go from here... Any

That is an old car- short of total restoration, I don't know what to suggest- maybe check the fuel system for dirt, starting with the gas tank- while you're at it, restore the entire fuel system- then restore the entire ignition system-
