I'm new to this
have a 95 civic with a b20b and b16 head dohc vtec with gsr cams and edlebrock adjustable cam. also a edlebrock victor x intake manifold with the adjustable throttle body arm fuel rail. \
having a problem, car at idle is crazy, wants to die and right before its about to shut off the rpms kick up, and while driving it backfires a lot. and has a hard acceleration. theres a vacuum fitting in the back were if i plug it the engine stalls but i have no idea were to hook up that line. its also got a check engine light on and i checked it and has a steady flash so does the mean code 1? I'm lost and can't figure this out.
!!!link to video:::
as you can see when i plug the unused vacuum fitting my car will stall it won't do it in the video because i just turned it on and it was a cold start.:
thanks for the help

That needs to be blocked off. You might wanna contact Edelbrock for the correct fitting size. Once you have the correct fitting see if you can cap it off with a rubber hose and a screw.

Make another video of the blinking CEL.

Seems like you have vacuum leaks, considering the issue you are having with that extra fitting. Cap off the fitting, any way you can, just make sure it doesn't have a vaccum leak.

What throttle body are you using? Is it clean and working properly? It may have a blocked passageway for the idling mode. Can you remove it, and swap in a known good throttle body?

With the fitting capped and the butterfly opened a bit, spray brake cleaner or starter fluid around the throttle body, intake manifold, gaskets and all hoses, any increase in idle?
