I have a 1991 z28 with TPI that is stalling out. When you are at low speeds like a parking lot the car starts missing it wont die just misses and runs like crap.

The guy I bought the car from said he had replace the injecters with bigger and better. Not sure if this has something to do with it or not. Thanks for your help

 

Could be injectors but try reading codes first. Bigger isn't always better. Standard for a 305 is 19#. What size engine are you running and have there been any power mods done to it? Do you know what size/brand injectors the PO put in and how long ago?
