Slp maf???? Starting last friday my SES light has been coming on then off then on and so forth. Today i brought it to Auto Zone to have it scanned and this is what came back.... code P1404, IAT - B Circuit Malfunction / EGR Temperature sensor Circuit. Does this sound like something that my SLP Maf sensor is tripping? The only thing ive done to my car lately is swap a Whisper lid for a TSP one (Stock maf size even though i have a 85mm maf), dumped the HPP3 power tuning and i had a cat replaced last friday as well. So prior to last friday my SES light was on all the time, so i wouldnt have known if any of those changes did anything. Please Help! TIA

Re: Slp maf???? I checked my wires they all seem snug. The only thing is the rubber groumet that holds the IAT sensor into the lid is ripped on one side. You think that could do it.
