On a Throttle Body Injection (TBI) system, the choke is typically integrated into the throttle body assembly. Instead of a separate mechanical choke like in traditional carburetors, TBI systems often use an electronic or automatic choke mechanism that adjusts based on engine temperature and conditions. This helps regulate the air-fuel mixture for optimal performance during startup and warm-up.
there is no choke it has idle air control valve it is tbi corect
you cant it a TBI
There is no choke on an injection system. The cold start enrichment system performs this function.
Choke is out of adjustment
no it does not it's fuel injected. It is most likely a TBI(4.3Liter )not Multiport (4.3 Liter Vortec)
That year don't HAVE a choke. Is your check engine light on ? If it is, then you need to have the engine scanned with an engine scanner to see what is going on. Problem could be the MAP sensor, coolant sensor,fuel pressure regulator. Any of these problems could be making it run RICH are LEAN. Fuel injection fuel system DID NOT USE A CHOKE.
YES
you can as long as you use your TBI heads if you want to use the vortec heads with TBI you will need a special intake manifold or a carb manifold with a adapter to mount your throttle body to the carb manifold heres some more info TBI heads will mount to the vortec block TBI intake manifold has 12 bolts vortec intake manifold has 8 bolts
yes they will
Its TBI Vin "W" is CPI.
It has TBI / Throttle body injection.
no such thing as a vortec 5.3 tbi
