I have a '93 Chevy S-10 with throttle-body fuel injection and 4.3 V-6, and it needs a new or rebuilt throttle-body assembly. Does anyone know of a source for these, or know of some service that can rebuild them for you? I know that rebuild kits are available, and I looked at a how-to video, but I think it's above my pay grade.

 

You should find them on ebay or Rock Auto. Does this look like the one? https://www.ebay.ca/itm/273770581799...IAAOSwXeBgZJcV

 

Yes, the one pictured is like mine, but it is incomplete and missing a lot of the parts I need to replace, and it wouldn't be of any value to me. I need the complete assembly.
I don't see anything else on eBay, or anything at Rock Auto.

 

I went to a local junk yard for parts when I had to do mine.
Didn't know **** about cars back then, but it was very beneficial to do myself.
Junk yards sell parts for about 1/3 the price of new, and you'll just have to buy new gaskets and seals.
