to work drove fine for about 3 miles, then all of a sudden truck
started bucking and sputering. Idles fine, even in gear. but cuts out
at about 2000 rpm. I did nto see anythign loose or any connections
missing that may have been possible while working. I am abotu to go
crazy. The truck is at the side of the road. Any help is appreciated!

Be sure A/C is off and also disconnect the A/C compressor. See if that
is the problem???

When did you last change the fuel filter?

Is there any fuel in the carb when you look down in there?

does your truck have a mass airflow sensor?

Because that is what you were working on last, so a PRIME suspect as
to what the trouble could be. Some A/C systems come on automatically
for a brief run (even in the winter) so it will circulate the oil in
the system. Also will come on for defrost with some systems.

Anyway if you disconnect the A/C compressor and you still have the
problem, then you can eliminate that as a suspect.

And if there was a problem with the compressor, it could place a large
load on the engine.

Probably not the problem, but since you installed a new one and that
was what you were working on, I would be sure that was not the
problem.

I wouldn't leave that vehicle parked by the side of the road too long.I
would get somebody with a vehicle and a chain or tow rope and get it
home.Especially in my neighborhood.
