89 with CEL codes 41 and 13

[SHO GoDz 89]

My car recently just started showing the CEL. Only a few days ago it started to come on and it comes on after about 5-10 minutes of driving (Assuming it happens when the car warms up).

I ran the KOER codes and got 41 and 13

41 Means the car is running lean, and 13 has to do with the IAC apparently.
I'm not too worried about 13, but 41 is obviously what I would like to know how to fix. I've never run the codes on the car before, but I cleared the existing ones and tested again and these are the only two to come up.

Any ideas?

The Idle control valve can be removed and cleaned. Make sure you have a replacement gasket first.

Code 41 can happen if the car is not "good and hot" when you perform the test.

If you don't want to try the test again, just replace the o2s.

Thanks. It probably is the O2's. I don't believe they have ever been replaced in the entire life of the car.
