How many miles are on it? You may just need to replace the spark plugs if you're getting a misfire.

I was getting the same type of issues and pulled the same codes, but also on cylinders 1,5 and 6. I pulled my lugs and they were toast. You need a 17mm wrench and some patience but its fairly easy to do yourself.

There may be some more experience on here than me.

List some more details

year
miles
yada yada

How did you resolve this problem? I just replaced the MAF sensor on mine and that was the fix... Temporary at least. Now looking into the root cause since I found oil on the MAF connections. Need to change air filter ASAP I think it's saturated with oil.
