Engine missing while accelerating

  1. I apologize if this has already been posted before. I'm new to this forum and am actually trying to help my dad figure out what's wrong with his '88 fox body gt. It's been in storage for the past 10 years and miraculously fired right up the first time. Two issues that I'm trying to figure out however.
    1.) It takes about 10-15 seconds for the engine to actually fire when turning the key.
    2.) The engine acts like it wants to stall when just prior to and after shifting gears.
    My hunch is there's an issue with fuel filter or pump or something with the fuel. Is there a way check exactly what's wrong with it? Is there anything else you thunk may be wrong.
  2. Could it also be an issue with the exhaust system - like maybe a plugged catalytic converter. When I have the issue the exhaust system sounds like a popcorn maker.
