Message	So I think my initial thought should still hold. That is if the OP's car will idle "fine" with both TPS plugs unplugged, then the O2 sensors are likely driving the ECU to hide a fuel problem or an unmetered air problem? I was thinking fuel because he passed his boost leak test, but I guess it could still be the AAC or a bad MAF signal? (although his MAF signal does look pretty normal at 1.1v) Any other possibilities?
