I was going to replace the EGR solenoid. Called two dealers and they said it is discontinued for the 5.0 and 5.7. What now??? Not exactly a part I would want to go to the junk yard for. Anybody heard this? Can the old one be rebuilt? What is everyone else doing?
All it is, is a solenoid that works a vacuum valve. Not rocket science, or "specific" somehow to a particular car. There's dozens, maybe hundreds, of GM vehicles that have a similar part. So even if GM has discontinued THAT PARTICULAR ONE, they're still going to be WIDELY available in the aftermarket for years and years to come. At worst, you might find that a vacuum nipple is for a different size line, or a mounting screw is different, or something like that. Or, that the one you get might be exactly the same, from the same mfr even, just in some other brand of box. Not exactly a Chicken Little "the sky is falling" scenario in any case.

Roughly paraphrased into modern English, and applied to figuring out what's wrong with your car:
The simplest explanation that fits all the facts is probably the right one.
I ordered from Rock Auto and they said not availiable, tried special order from Pep Boys, same thing, called parts America, they have four different makers, all not availiable.
Since the EGR solenoid is not availiable anywhere in the world for my 91 5.7l TPI, I was told to look into a 93-97 LT1 EGR solenoid. The LT1 solenoid is supposed to have the same wire connection as the 3d gen connection and it should work the same. The only apparent difference is supposed to be the bracket which should be easily modifiable. Can anyone confirm about the connection and will it work?
1fastam - thanks a ton!, schucks is the same as parts america, I had called them last week, they said not avaliable and no availiable date. After reading your post I called again and they showed 1 unit in stock of the GP Sorensen Egr Vacuum Solenoid Valve part # 7799618. They physically checked stock on the item for me and it's on it's way to me. Thanks again!
