Would anyone know why anytime I take my foot off the gas, the engine stalls out?? Idles terrible and it sound like it's cammed when it's not lol. Checked out the iac, cleaned it reinstalled it, did the same thing, no check engine light when I keep my foot on the gas to make it idle. Unplugged the tps it made it a lil bit worst. Plugged it back in and it was back to the way it was before still not idling on its own without my intervention. I'm kinda lost rn, it would be appreciated if someone...

Engine won't stay on unless foot is on the throttle, HELP
