Does anyone have a PDF copy of a service manual for a 1988 GMC 1/2
ton? I sure would appreciate getting a copy to try and solve a few
problems that my dad has with his pickup.

Post some of your problems. Many of us have or had Chevy trucks of that
vintage and might be able to offer some advice or answers.

Cheers - Jonathan

The problem he is currently having is that the engine (305 CID) is
acting like it is not getting any fuel intermittently. Even when it is
first started it seems to idle a bit on the rough side yet when we
look at the spray from the injector nozzles it looks to be a steady
even pattern.
To give you some background; the local fuel suppliers now are using
some sort of different gasoline that cleans everything...... or better
put, dislodges everything!! On two occasions we had to change the fuel
filter and the injectors on one occasion since the spray pattern was
not normal. This cured the problem only temporarily. We suspected the
tank to be dirty or a faulty fuel pump. We removed the tank for
inspection and found only the usual amount of small debris on the
bottom which we clean out. We put the fuel pump in some fluid and
function tested it. Seems to run and pump normally.
When the engine is started it seems to not run as smoothly as it did
previosly and at higher RPM it runs rough occassionally as well.
Anyone have any similar occurance...... or any other suggestions as
how to repair this nagging problem.
