Please help! My truck is sick.

It was driving fine four days ago.

Now, after it has warmed up it will suddenly sound like it is sucking air and cant go past idle. It won't start warm, only cold.

What changes after the engine is warmed up?

I have a video of it:

Any help? Please!

Choke is stuck closed...
After warmup choke opens if its stuck closed it wont start when its warm, pop the aircleaner of and push down on the choke plate or spray with a bunch of carb cleaner... i don't remember if u can see the choke plates on those carburated fuel injectors (lol) but I'd start with some gumout and go from there....

Ok. How do I check that?

Look at above post

I looked under the throttle plates and didn't see anything related to a choke. Wouldn't the computer just enrich the mix via the tb injectors?

I did spray everything in the TB with carb cleaner and unplugged and repluged a bunch on connections.

This time it seemed to warm up slower. (also discovered the temp sensor wire is loose)

Could a stuck injector have caused a lean condition after the computer tried to stop enriching the mix (choke)?
