They replaced maf, fuel pump and spark plugs and I put in O2 sensor back in Nov. Fan clutch and power steering pump were also replaced in Nov right before it went to body shop. I know those two things would not have anything to do with the codes being thrown. Though, for some reason the fan clutch is working better but it still has that whining noise for the first 30 secs which it never had before. Also, kind of sounds like there is a slight droning noise.

Could a bad connection somewhere actually damage the Maf? Up until this point when I have replaced it after it throwing a code the cel wouldn't not come on for several months so I assume they were actually damaged. The output of the computer has been ok when they have checked it. So I don't know.
