The same web site lists the part for around $65 bucks. What I’ve been doing lately when it comes to replacing an external part of something I suspect but not sure of - is go to a junkyard and get the same part for about $10 – 15 bucks. If that’s the problem then the next time I’m at the parts store I’ll pick up a new one. It’s a lot cheaper that way.
Here are a couple of web sites you might find helpful. They include prices, pictures, and locations of components.

Sounds like it’s getting too much fuel. Maybe one of your sensors or connections is faulty.
Have you had the codes read yet? If you don’t have a reader of your own most part stores will read it for free to get your business.
You might find the following web site helpful in explaining how the different sensors interface with the onboard computer, which is what actually runs your engine.
In today’s engine, pumping the accelerator doesn’t do it. We like to think we’re in control but just like 2001: A Space Odyssey (1968), HAL has final word.

Please advise if you can help any more.

Sounds to me like it has something to do with the MAP sensor or EGR valve. In the past I’ve had to replace them on both Ford’s and GM’s. Sometimes they have a rubber or metallic line running to them that comes loose. Sometimes the sensor or valve just wears out.
There’s another possibility on the EGR valve. It can get carbon trapped inside it causing it not to open and close like it should. GM is bad for that. They make an after market gasket for it that has a screen built in to help alleviate the problem. The gasket is less than $10 bucks. The MAP sensor or EGR valve are pricey.
Be advised, in the state your engine is in now it is poring out tons of carbon monoxide. Speaking from experience, do your work outside the garage vice inside the garage. My head still hurts every time I see the dent in the wall from where I fell out from being overcome by the CO.
Good luck.
thanks again,

my question is should i try and rebuild the engine or swap it out? And will an older 4.3 fit my truck without any modifications? I have the 2.8 right now, '85 s15.
I just want ot hear some opinions on the matter. I am hesitant to fix the car, as it seems to be going downhill. Would it be better to put that money towards a down-payment on a new car? If I fixed these problems, how much more life do you think the car has? Any advice at all would be great...
I have a 99 auto regular cab it has only 53K, only have done fluid and filter changes, no repairs.
I have 3 GM 4.3's including one in a Sonoma. They all have their second water pump in them but after a minimum of 70k mi.
Before I throw money at parts I don't need. What is the cause for the truck to fail the 15 mph NO test?
O2 sensor, cat. converter, EGR. could all be a cause, but if try to test each one the best I could.
What about the EGR vacuum soleniod?
Any advice would be great! Thanks Kevin

On the S-10 that I drive now (92, 4.3Z) I had a problem similar to yours that was bugging me to no end. Finally I accidentally came across the problem. The vacuum line that runs from the PVC valve to the front of the throttle body had a bad vacuum leak. As it turned out the plastic elbow had a serious crack on the bottom of it that you wouldn’t normally see. After I replace that it ran like a champ.
Suggest you go hand over hand tracing all your rubber vacuum hoses back to the intake manifold. It’s time consuming but on rigs that have a little age on it like yours and mine, there’s a good chance that the vacuum hoses could have an Aortic Aneurysm.
Good luck and keep us updated on developments.
