I recently bought a 1994 s10 Blazer, it had a rough idle, I thought maybe it was the cat converter, so I replaced the entire exhaust system. It didn't cure the issue. I just now recently replaced the spider injector and now my problem is worse.

I have no power, it bogs out bc of how much gas it is getting, my intake manifold is cold to the touch, I take it that it is flooded right now.

Can someone provide an install of the injector, maybe I put the wrong nozzle in a hole? I'm not getting any codes just no power and a somewhat smooth idle and a horrible smell of gas.

What should I do next?
