I’m trying to figure out if these are replaceable, the problem is I don’t know what the **** they are called. I am also wondering if they are nothing more than plastic clips for the fuel injector wires. I have included a couple of pictures for your review. This is the throttle body on a ’93 Chevy 350 Silverado 2500 4x4. If you are wondering what happened, the truck wouldn’t start so I replaced the distributer cap, rotor and plugs. I had the air cleaner off, started the engine, then engine died and the throttle body caught fire. Well that is the long and short of it, your comments are appreciated.
