I just has my 2002 Mustang GT up at autozone to check the codes for the Service Engine Soon light and here's the codes they came up with:

P1130
P1150
P0171
P0174

I was already planning on changing the spark plugs, and the autozone dude recommended that I clean the MAF and throttle body/intake while I was working on it to see if that was the problem. Any other ideas about what I should look at if that doesn't do it??

And, one stupid question to get out of the way - does the engine need to be running when spraying this cleaner on the MAF and/or Throttle body/intake??

Those are codes indicating the system is running lean on both banks, here are the possible causes for P0171 and P0174, click here for P1130/1150.
