see 2 pictures of my shield
I guess the front end is coming off this weekend.
And then is it a shield attached to the bumper that 'semi-tightly' wraps both filters ?? (top & Bottom) ??

I understand Nissan throwing a Trouble Code, but disabling the vehicle seems dangerous to me.
Of course, I have modified said vehicle, so my heirs owning Nissan any time soon seems unlikely.

That looks good, that's probably not your problem.

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 ?
