Drove without oil cap. Now getting SES codes

Silly me! Did the OFHG today. Forgot to put the oil cap back on after adding some oil. Drove about 2-4 miles to a store. Noticed the engine was having few hiccups along the way, and idling was a little abnormal. So after putting the oil cap back on, the car ran like normal. But after about 15-20 mins of driving, SES light came on and gave the following codes....

P0174 (System too lean Bank 1)

P0171 (System too lean Bank 2)
Misfiring cyl 1,2,3,5,6

I assumed the P0174 and the pending codes are a result of driving without the oil cap. I dont think I did any harm to the engine and clearing the codes should be fine. I just want to get a second opinion. Any thoughts?
