I wonder if the hesitation issue is being caused by the PCV fitting being loose. Has anyone with the hesitation issue tried taking some Teflon plumbers tape and putting it on the PCV fitting threads then tightening it as tight as you can by hand? Maybe the problems are caused by air leakage from around the PCV fitting throwing off the MAF sensor under high vacuum.
