My check engine light came on today and right now i'm trying to get the cover off to check a code (first time ever doing this). The write up says to get the cover off with a "quick twist of the screws". Well mine only has 2 large circular plastic "screws" with no face (ie: flat, philips, etc). The surface of these 2 are just plain and flat so there's no way to get them off. I tried prying but didn't work. Thanks

 

Nevermind, pryed really hard and it came off.
