Coed With Truck Problem
Sorry to disappoint some of you - the coed is my daughter's college roommate.
To add insult to injury - its an S-10 chebbie, 1992, 4.3 V6, TBI??. Seeing all the recent non-Ford postings here, emboldened me to toss this out.
Being a Ford man, I know little about this truck, but told her I would see if any of the great FTE guys could help. I rode with her yesterday as she was trying to describe the problem. When cold, it starts fine but on take off, starts bucking and hesitating something fierce. Some fine gas pedal finnagling keeps it going. Once thoroughtly warmed up, it runs fine. By thoroughly, I mean driving for a long time.
The thing has a carburetor and what must be TBI. Any thoughts?
BTW: She is very cute.

There are several things that can cause this. The older fuel injected engines dont have injectors but do have a TPS and a control celonoid that is attached to the trottle body. Dont over look a clogged fuel filter. Bad spark plug wires and dirty worn spark plugs should also be eliminated.

TBI= Throttle Body Injection
It's basically 1 big injector. There is plenty of info out there on how to trouble shoot the system. More than likely a sensor is out. Check for a MAP sensor code.

On cold start, fuel injection systems, including throttle body generally uses the engine coolant temperature sensor to determine the amount of fuel needed to keep the engine rich enough to keep from dying. Check this sensor and it's circuit.

Coolant temp sensor, Intake Air Temp sensor, and fuel pressure are all possible culprits.
As stated above, TBI is fuel injection. On this particular vehicle, there are actually two injectors, in a single unit, mounted like a 2BBL carb but with GM's own unique three bolt mount.
Shipboy is referring to the old feedback carburetor system, which is not fuel injection but uses a computer to control the mixture from a carb.
If the check engine light is on, it just takes a paper clip to pull codes.
