Well for the record the replacement MAF worked flawlessly, I then swapped the 85mm 5 wire MAF and it did not work fine, then literally due to a simple mistake of splicing the crank low ref wire instead of the maf wire when installing the MAFT Gen2. Well I thought maybe my Craigslist MAF was bad so I grabbed a 85mm 5 wire reman MAF @ Autozone. The 85mm MAF from Autozone looked identical to the one I was trying to replace. I then realized the problem above but went ahead and tested the two back to back...almost identical frequency output. I returned both the reman 87 style MAF & reman 85mm MAF back to Autozone but guys both the remans worked GREAT..
