Question Code and idle issue

Alright guys ... I’m throwing codes ...my check engine and traction control light come on. I have around a 1100 rpm idle... changed plugs, cleaned IACV and new IACV gasket. And still codes. Also have high hydrocarbons. Ran sea foam through me car as well. I though about the O2s and maybe using foulers to space them. Any help please!

You do realize that your car reports specific errors and doesn't just generically "throw codes," right?

You’re wasting money firing the parts canon at the car.

How to get the codes:

So many potential areas that could be from a poor seal on the gas cap, worn brake pad sensor or...? Getting the blink code will be specific on what to check-replace.
