Just as it says, Stock 5.3 with a P01 ECU. getting random misfires on all cylinders. (annoying but no knock) and when im driving or just gagging the gas at idle I get sputtering randomly that coincides with the MAF hz going from 2500hz-4000hz up to 10k+ hz in a direct spike when it shouldnt be. MAF is a new Delphi 10043 unit. attached is a log of it just stabbing it at idle and even gradually going to redline.
Is this an issue with the tune or just a bad MAF sensor? also would it cause random misfires to be detected throughout the RPM range idle-6200?
Thanks
Well apparently my logs didn't upload, I'll add them when I get to them this evening.
