    Been have a surging idle for months now and I am fed up.
    This is what I've done so far.
    Clean the TB including taking off the IAC and cleaned.
    Ran SeaFoam through the vacuum lines and in full tank of gas.
    Cleaned the MAF, twice.
    Checked all vacuum line using Propane technique.
    My CEL code is a P1135.
    Would this make my Taco have a high surging idle?
    I know the code is to replace my O2 sensor.
    Would a bad A/F sensor make my truck idle high?
    I may have to bite the bullit and purchase it, but what if the P1135 is something else?
