Hi,
Title says it all. customer swapper out his 4.8 to 5.3 from gen 4 to gen 3.
He changed reluctor wheel from 24x to 58x, all new llifters, non vvt cam (stock), springs, pushrods, valley cover & timing cover.
car misfires at idle only in DoD cylinders although vvt & DoD are tuned out.
I searched the forum and many faced the issue though no one posted the solution.
any input will be much appreciated.
