Discuss: Intermittent Engine stumbling/Kick only at idle, Feeling it in the seat Options

What could cause this? What are your ideas.

5s-ge (Soon to be boosted, yea, not a 5s-fe, or 3s-gte) ran great up until the other day when it started to kick and i noticed oil in spark tube 2, small amount in 3. The valve cover seals show no sign of leaking into the plug wells. Gas milage is also ****, probably due to the missfiring in which ever cylinder. Im just curious if this is a chain of issues or if its just due to the oil. Once it gear the stumbling subsides but it still present just not as violent and often. Once you get moving you cannot feel it what so ever, altho there is a small loss of power

Idle@718RPM
Compression: 1-215/2-205/3-205/4-200
Fluids: Full
Tune: Modified 3s-ge OEM programming (-0097, 0.23+, 2.338^)
Econ: 21.6mpg (was 27.8)

well okay, for lack of mentioning it early the oil hasn't made it to the PLUG WIRES, they are not soaked and have not swelled up at all. as for a valve cover gasket, it was replaced already this is a BRAND NEW engine see my thread in forced induction, as well as, as long as u clean the gasket and valve cover properly u can reuse an intact gasket.

I pulled the plugs and drained the oil, issue seems to be gone, im sure oil will appear and I will do it again.
