After $600+ of dealer work, i think the basic problem is still there. Dealer diagnosed and replaced coil, wires and plugs. Also indicated possible injector issue which were addressed through cleaner. I have run the for over 6 hours while using Seafoam in the tank (2 cans for 25 gallons plus a third can at the next fill up of 27gals).

The car runs great at highway speed, performance appears to be 100%. At stand still it still has a hard miss. Is there something else we are missing (btw no codes or no check engine light)?
