Hi all. looking for opinions/cause of a CEL i just got(first one too). I don't have a scan tool and it says CHECK EMISSIONS. I was messing around in the engine bay a few days ago trying to put a clip for a trickle charger on the positive terminal which meant moving the air filter neck up a bit and i did notice the filter joint gasket seemed loose after. Could this throw a CEL if i it was improperly reinstalled? and will it go away once i readjust it?
