If the codes are gone, the problem is cleared. Don’t worry about it unless it comes back. Do your regular services and maybe extras the previous owner ignored… like a brake fluid change and maybe a transmission oil and filter if it is an automatic.

I think you’re set if all the codes are gone. Did you even have to clean the MAF?

I’m glad to hear that man. Thanks for the help. I was planning on bringing it in to have all fluids changed, oil change, spark plugs, etc.
