got a steady check engine light yesterday afternoon, but I think I've fixed the problem

When I changed my plugs last week, I dropped one of the old plugs down between the exhaust manifold and the metal cover that goes over it. To get it out, I had take out the screws that held it on and pull it back a little. When I put everything back together, I didn't tighten down one of the screws



the owner's manual and a few posts I found on the forum said that a steady check engine light was a problem with the emmissions system, so I'm thinking that is what caused it, and after fixing the problem, the check engine light should go away after driving the car for a while. (How long?)

While I was at it, I also checked the codes and this is what I got. All of them were history codes, so I don't think there are any problems.

edit: yeah my engine bay is dirty, sue me

 

never mind, the check engine light went out as soon as I backed out of the garage.

 

Congrats on the fix. That's what really counts!

 

Thanks Patches. I'm learning as I go; one of these days, I'll get through a job without any problems.
