Recently my "check gauges" light has come on. It will come on randomly for about 30 seconds and then shuts off. Its a intermitten problem and is never consistent. I called and talk to Edge since I thought it might be the Edge going bad, but they siaid its most likely the IAT sensor, which takes the temp in the air intake? Is anybody familiar with this at all?

I then did a little research about the IAT and said it can be clogged with soot and needs to be cleaned. Again I am not familiar with this at all and have emissions coming up and dont want to fail!

Any suggestions would be great or if anyone has had this same problem.
