OBD-II codes without check engine light

Is there a possibility of codes being stored in an OBD-II computer when the check engine light isn't on?

The car is a 98 Camry (not mine) that randomly stalls when started sometimes. I can't get at the IAC, because it looks like it requires removal of the throttle body, which is just not happening right now. The check engine light is not on. I would buy a code reader if theres a possibility of some codes hiding in there...

OBD-II will have "pending" codes that are stored and can be read by a reader. Pending codes are usually one time occurrences that are waiting for a subsequent second or third posting before flashing the CEL.

Autozone or any of the other big chain parts houses usually will read and can clear any "pending" codes.

Then they gave me a loaner tool kit and told me to remove the battery and bring it in. It was a 47-piece socket kit, which had a total of about 15 pieces in it, half of them extensions for a drive size that wasn't even in the kit. But I'll ask 'em to pull my codes, lol. Wow, im

You could always go on Ebay and get a scanner for relatively cheap. If you do that, get one that is "CAN" capable to cover the newer cars. I support 5 vehicles in my household and found it to be a good investment.

If its the 4cyl camry- you should be able to get the IAC off without removal of the throttle body. although for some reason they like to use phillips head bolts to attach it to the TB. also be sure and check all the vacuum lines around it. i had a similar problem with a friends 97 camry. the IAC fixed it, but the vacuum lines had also seen better days.

Got the thing fixed, and it wasn't the IAC, but the ISC or something like that, and it did require removing the throttle body, which wasn't really that bad after all. But yeah, it looked like it had been barbecued...
