as the title describes i have a really odd issue. a while back my 06 cobalt LS had some issues starting up. It would rumble at just under 1000 rpms needle bobbing up and down and the engine making noises like its trying to start. finally it would either die or start up. Chevy was going to charge me way too much, so i had some friends at a local Honda dealership run the codes and all they could figure out to help was to clean the air intake (some oil ended up in there). my assumption is that it has to do with the oil somehow getting in the air intake because it started up fine after cleaning that out. my problem is that it's back and now especially after putting gas in (regardless of previous gas level) it will not start without a lot of revving and i know this cant be good. everything is stock, though there is a k&n filter on the air intake, which is where i'm finding the oil. i tried to get a video but i couldn't replicate the issue (it happens randomly it seems), ill get it next time i put gas in if a video would help
