First, Thank you for your time & help.
Let's say it's a Lower Filter/maf issue that you said gave people similar symptoms.
Right now p1239 points at Bank 2. I can switch the maf extension cables inside the engine compartment. If I switch them, & I AM getting turbulence hitting the Lower filter, might it then show that the Throttle Position Sensor Bank 1 is faulty ?
if so, Then I could work on that issue with the mafs. & could use a good description of the shield people are making.
if it still throws the same code1239/bank2 --> could I eliminate the maf sensors ?
