but if I'm cruising and then quickly come to a stop the engine typically will die. It seems like it needs way more air because it kind of sounds like it's suffocating. But, if i give it some gas for a few seconds it'll settle into a high idle. I don't really want to give it more gas in the idle mixture because it idles fine.. it just seems like it's sluggish about "shifting gears" or something.
Can anyone understand what i'm talking about?

Please help, after so many problems I feel so close to victory

Thanks, y'all.
