Slowing lose prime while engine is running & re-gain prime at restart? I have a miss in cylinder 1 and have changed the spark plugs, wires, coil pack, and even the intake gasket and still has a miss. There is a ticking noise coming from around the cylinder 1 area.

this happened just all the sudden one day while driving the car and didnt seem gradual. I have checked all the fuel injectors and they all spray fuel equally. Since it has a ticking noise could that be a lifter losing prime and worn out? Could a lifter with no prime mess the lobe up on the cam?

Yes to all. A lifter can collapse and pump up as well. If it is, I suggest replacing the lifter in question as it is causing an driveability issue.
