I know this code has been discussed many times, and I've even looked through troubleshooting guides, but before I spend any more money I just want to get a couple specific answers.
I got this code once before, and jiggling the MAF sensor connection fixed it, so I was almost certain it was faulty when that didn't work a second time. Of course, I tried cleaning it first to no avail. Replacing it wasn't the problem either. The next step I took was to check my front o2 sensor. It was loose. I decided to unscrew it all the way and twist it the reverse way so it's wire would untwist itself as I screwed it back in, but I found the threads were seized and was unable to get it back in.
Now I'm looking at $200 for a new one from autozone, which seems a little high for me. Maybe they forgot to mention a core fee? What are my chances this was my problem? After being out $130 for the MAF, and $150ish (If there was in fact a core fee attached) if I still have a CEL after tomorrow, I might damn near shoot myself.
