You can look the details of the codes up in the codes PDF from the FAQs (get the one for your car era). (Briefly, P0300, P0301 & P0305 are misfires, P1316 is another misfire-related and P1582 indicates specially stored data you can normally ignore.)

You should be able to use a car wash (though I wouldn't LOL) but they do tend to be rather aggressive and find any weaknesses as well as being rough on paint etc.

As Gus says, no need to take the bonnet (hood) off.

Izabelle - Don't try the above. Just get the codes.
