95 geo hesitates on accel and sometimes stalls after warmed up while at a stop

It runs fine when cold or even warmed up in very cold weather. I have replaced the fuel filter,air filter, temp sensor to computer, wires are new, used 2 cans of gas treatment. The weird part is how nice it runs when cold versus how bad it runs after warmed up and even worse after warmed up in the summer…any thoughts??? I would hate to take it in and have them throwing parts at it over and over

If this is tbi fuel injected clean the inside of the throttle body and throttle plate with spray carb cleaner, an old toothbrush and clean rags.
