I would agree with Ahsai and Silotwo.

Reads like at least one intake valve lifter in cylinder 5 is not working right.

Is there any noise, valve ticking? Does the engine run/idle rough?

There is a road test -- takes two techs -- to check out the valve lift function. One tech drives the car the other monitors O2 sensor readings and observes any abnormal reading that indicates one or more valves are not opening completely due to a bad lifter.

Just be sure the plug and coil have been eliminated. No way you should have to remind the tech of this but there have been misfires traced to a coil. While the coil was not bad its connection at the wiring harness was marginal and this accounted for the misfire.
