I have a 1995 chevy k 1500 350 tbi it hesitates when trying to accelerate changed plugs wires cap and rotor it dose have aftermarket tbi and performance intake it dose it hot or cold thanks

Check if it has it; EGR valve and controls, throttle position sensor, and fuel pressure.
Process of elimination. A real time scanner may be of help

Mass air flow sensor would be suspect.

Dirty air sensor

Assuming it’s not your transmission
Or fuel pump
Sounds like it could just be a timing needed
(Self chokes on extra fuel, until rpms start to rise)
Ty new air filter

If press gas then wait 1/2-2 secs
Probably air/fuel mix problem

You have fuel supply
Air supply
Spark
That’s all that is needed
I always first suspect air flow as it’s cheap to fix and very common

Replace the distributor, $50. on line, the trigger coil wire is shorting out. The 50 bucks was well worth it. 10 mins truck ran great after that was done!

Hesitation with TBI is sometimes a dirty Injector, make sure you have a good fan pattern on the injector and make sure its responcive. use a nylon wire brush to clean the tip, and alot of carb cleaner, also make sure that your butterfly moves freely, they tend to get gue/carbon build up on them and this will also cause a hesitation
