I don't agree. I think this could be a problem with your secondary 02 sensor of you catalytic converter is clogged. You can pull it off and check to see if it is clogged or you can just spring for a new Catco or similar. They won't be more than 100 bucks and are better than OEM ones (if you are modified at all).

are your wires shielded correctly?When did the problem start?have you install anything or unplug/replace/fix any wires recently?

had same problem...are you getting any other cels?if not try to get them...unplug a sensor at a time.....make sure after pulling each one you check cel code to confirm the ecu is registering sensor as unplugged and especially check to see if the right code comes up for right sensor....example: if you unplugg your knock sensor and iat fails, or vice versa or anything like that then you have allmost found your problem....also check to be sure that all sensors have the correct number of wires going into them...thermistors=2 TPS=3(i think w/o looking.check repair manual for specific number of wires and wire colors.)knock sensor=1 so on and so forth.
hope this helps and if not then search around some more and learn more about your electronic components under the hood
