    Idle dying

    Car runs perfect on normal driving and WOT. When its idling there is a fluctuation on the FPR gauge. The shutdown happens randomly, it could be after minutes or it might not happen at all.

    Setup :

    Radium rail with dampener
    Driven Flex Fuel Kit
    FIC 1650
    Walbro 450 re-wired.
    Stock Cams and Stock Motor just bolt ons with a EFR kit.

    FPR at idle is 39-41psi.

    I swapped the FPR and no changes were noted. No fuel leaks no boost leak, everything seems where it should be. Any insight ?

    Today the plan is to clean the MAF sensor, a code came for the O2 sensor so will replace that as well

    Please let rephrase your question.
    What is a normal TPS reading at normal idle at 950 rpm?
    I ask because I also have some idle issues, especially when it is cold and with the a/c on.
