After letting my Civic run for a little bit, it begins to idle very ruff. I've cleaned the iacv multiple times and it eases the idle slightly, but after a little while it goes back. When I pat the gas lightly and hold it in that position, the RPMs go up for a second, then almost stalls for like a minute and then it eventually stalls. Is this caused by a bad fuel injector?

try cleaning the pcv valve. It goes from the valve cover by the distributor to the intake. Just take the hose off by the valve cover side and spray some brakleen in there and you'll feel air blowing out when it's running. There's a couple write-ups on how to do it but I don't have the link handy

I just replaced the injector o-rings on mine and it fires up faster. If yours takes a couple turns it should help that too
