Suggest you read the first 2 links below in my signature.

Keep in mind, many times even if you find a single problem like the DISA that seems to clear your codes, you may in fact have other problems.

The only way to verify you engine is running properly is to verify fuel trims with a scan tool that can read real time data.

Also while you are at it, verify you coolant temp is correct as well, see this link -
