While doing some scans & fine tuning for MPG.
I saw that when the car goes into boost the MAF & VE go right to a lean 12.5 from a rich -5.4, 9.3
Why?
What is busted?
Or needs fixing?
One other, irrelevant...don't know?
I have a miss, Probably a plug or two, changed them less than 2K ago, the miss has been getting a little worse as time goes bye.
