Help me out!!
Also a couple of weeks ago my spark plugs were changed and 3-4 days ago my CEL came on. I looked to see if i saw anything out of the normal and i saw my #3 spark plug wire was moving alot and a exhaust leak like noise was coming out of it. I took of the wire and i saw that the spark plug was loos. I figured that the idiot that chaned my plugs(me) didnt tightnd it. I want to know if the CEL will go away by itself.
