Stumbles and misses when accelerating

1988 Saab 16 valve Turbo convertible, it consistently stumbles when accelerating and sometimes may stall; it might be hard to restart. The car has 153,000 miles, garaged, well maintained. When I initially start the car, it starts right up and idles perfectly. Problem arises when accelerating while driving. Searching through old posts I have put in new Bougicord wires, new NGK plugs with proper gap, and Bosch cap. I put in new Bosch fuel pump with working pre-pump, new Bosch fuel filter. Checked both fuel pump relays above ECU- OK. I have switched out the following components with known good ones, ignition control module, AMM, ignition coil, APC control unit, and ECU. I have gone over all of the turbo plumbing with a fine-tooth comb - no leaks. All vacuum tubing seems to be in good shape - no leaks, turbo bypass valve / hooter valve OK. No leak in vacuum hose to Fuel Pressure Regulator. Vacuum advance on distributor seem to function properly. None of my attempts have located the problem. I am running out of ideas - help - please!
