The service engine code kept coming on and referencing stuck injectors.
After 5 trips to the dealer to flush the injectors, the problem
continued. The service crew had run into this before -- for some
reason, when the valves get gummed up and stick, the engine mgmt code
that comes up points to the injectors. I guess it was only through
experience of having been there before and witnessing the same symptoms
again that lead to them to the valves.
But if the valves and guides were just carboned up, and the compression was
good and didn't leak down they could have at least attempted to run GM's top
engine cleaner through the motor. I've used it in the past and it works
wonders on gummed up motors.
yep, that's the stuff... there was this poster on the wall showing how clean
it made the valves after using the stuff.. Damn, I've got a couple engines
that could probably benefit from that stuff. Too bad the guy went out of
He also had a stockpile of this platinum-metering system for gasoline cars
with carburetors... it would mix platinum with the fuel and supposedly made
you get better gas mileage...
..something else sets off my B.S. Meter... the 99 trucks no longer
offered a 5.7L. 4.8 or 5.3L GenIII V8s, no more "classic" SBC.
(or a 6L in a 3/4 ton)

for a bit longer, but the new series trucks swapped engine types at the
Not true, I have a 1999 K1500 (not Silverado) that has a factory 5.7 liter
in it. They consider this the early 99 as it looks like a 1998. The
Silverado is considered the new 99 body and they came out in mid 1999 with
the 4.8 and 5.3 liter.
Mine was made in November of 1998.
So it's a model year 99 with a 98 body style and a "classic" SBC in it?
Argh. You mean you could get a 99 Chev/GMC fullsize truck with both
body styles and both engine series? Boy, isn't that going to be fun
when trying to get parts in a few years...
But the problems will start to happen in 5 years when the local car
parts place doesn't list early/late anymore and starts to blend the
catalog together - new style oil filter, old style spark plug wires and
you're the second owner... it just ends up being a pain whenever you
need parts and it always takes two trips...
I owned an 82 Plymouth Caravelle. In the USA, that was a K-Car - FWD
4cyl. In Canada (where I live) it was a RWD V8 (Plymouth Gran Fury) or
a k-Car... so parts shopping was always a blast... eventually you got to
looking up parts for a Dodge Diplomat instead...
