Done....Some improvement but
Rafi..Thanks! That did the trick!
The car still hesitates/lugs on a sudden start from stop BUT after FPR change at least does not conk out. I suspect the FPR was probably not bad just a little tired. I drove it this morning but weekday traffic is not the time I wanted to check higher speed acceleration for any hesitation.That will have to be on a nice quiet early Sunday morning :-)
So in summary:
Fuel pressure checks as I mentioned above, it has a new fuel filter after which the hesitation/lugging appeared when pushing the accelerator hard from a complete stop. If I press the accelerator slowly then there is a smooth acceleration and no lugging.
And it has a new FPR so where do I go from here? Any experts interested in providing additional areas to check out?
