Don't know if it helps but my 88 350 TBI had bad hesitation if you gave it gas quickly would die if you didn't let off, acted like it was getting flooded. Would do that in park or reverse/drive too. However, if you slowly pressed down on the gas pedal, it would do fine. Check engine light was on so I checked and I had a code 22, TPS low signal voltage. Changed out my TPS (throttle position sensor) (Along with checking 5 volt from ECM, it was good, but the connector was bad on old TPS so it wouldn't allow the plug to be fully inserted) and now it runs like a champ. Have read that you may or may not have a check engine light. Might want to check yours to see if all is good. My Haynes book has test procedures, so wouldn't think it would be hard to find it and check into it at least. New TPS only was $28.xx at Autozone.
