I have a 91 chevy s-10 pickup truck, when its cold it runs great, once warmed up though its very slugish and want to cut out, on start off it bogs down and almost shuts off i have to punch it to get it to go...and ideas?

check clutch

You need a dealer, there is a real problem going on here, way over the head of any home do it yourselfer. The main reason is the special tools required to interface with the control modules that are throwing these codes

The catalic converter is plugged up in the exhaust system.

check to make sure the catylitic converter is not clogged.

First check for any cracked pipes leading into the intake manifold If all OK (with no codes showing it probably is OK) try checking the fuel pressure regulator. If you smell fuel from the pressure regulator vacuum side arm (when the vacuum line has been disconnected) it needs to be replaced.

If its an automatic chk. for bad starter switch under dash, if its a standard shift chk. the clutch switch witch is under the dash too.

Sounds like fuel filter.

tps sencor or maf sencor

try giving your truck a tune up cap,rotor button,plugs wires mine did same thing changed it now works and runs fine

Don't know if it applies to your diesel but most later gas engined vehicles have a 'cold start' valve that supplies additional fuel to the fuel/air mix along with boosting the idle speed until some warming of the engine is sensed.
