The limp mode continued to happen and happened again, again, again and the fix was always the same. Clean the MAF, swap the MAF, rinse – repeat. So since I did begin to notice it was always the same side -Bank 1 (passenger) - I bought jumper cables that let me connect the right wiring to the left MAF and the opposite is true.

Drove, limp mode showed up, codes said Bank 1 (pax side). Note that this is now years later ater having grown accustomed to limp mode (muscle memory?).

Regardless, I had an epiphany! so I chopped one of the jumper harnesses in half and then chopped off a section of the Bank 1 MAF connector wiring (cut back several inches into the car harness) and spliced in the newly created pigtail.

This new connector and section of wiring fixed the issue and it continues to stay fixed over the past several years and several 10’s of thousands of miles.

Not to be happy with having it fixed, I decided to re-fix it. So I ordered two pigtails from a reputable eBay huckster and then replaced both sides using proper heat shrink splices, staggered, wrapped etc. Looks and works good! I claim victory!
