lately my car has been stalling when I pushed in the clutch so I cleaned the iac. Then it started idleing at 2k. So I replaced it with Autozone and I ended up with a 3k idle. So now I put the original one on and unplugged it. now it idles just over 1k and runs fine. also the cel isn't turning on.

Should I be worried about the cel not turning on when unplugging the iac?
