2000 5.3 hard to start

[KE5PRQ]

i have a 2000 chevy with the 5.3L thats hard to start when its warm. it has no problem when it has set but if its shut down for less than a coulple hours it cranks but wont fire up, untill i push the pedal down, altho sometimes i can get it to start without using the pedal but it takes a few tries. it smells like its rich but it runs just fine once its going. i just did plugs and wires, new air filter. the throttle sticks sometimes in the closed position so i figure i need to clean the intake. its has almost 60k on it

Welcome to AF.

On a 5.3 hard to start hot always look for gas in the vacuum line on fuel pressure regulator.
If gas linkage is sticking clean the TBI buttery fly flipper and housing .
TB/carb cleaner and a old tooth brush does a good job on it.
If you help on yours it is best to start a new post.
