Thought I would follow up, (for the benefit of others) after going through a couple of cans of fuel injector cleaner (two tanks), and a mass air clean. I took it to the shop, after $350 and a new set of plugs I was told they got it. When I went to pick it up, they announced it had the same issue and leave it for another day. Next day they announced the issue was abraded wiring in the harness, near the firewall and when the engine torqued it caused shorts, (the solve was to put a split rubber hose around the wiring) they discovered it by shaking the engine a lot (old mounts) or so I'm told. In the end $775 ouch, but so far so good.
