If it were the oil shorting out the secondary side of (I assume) the #4 plug, it should misfire and set a code, but I have seen this before on M111's, just like 104's. I'd be concerned that becaise you're having a noticeable decrease in performance that the engine control module isn't recognizing misfires, maybe because the ring gear (crank angle sensor) adaptation was never "learned" the last time it was lost (by a dead battery or whatever may have occurred). This is a critical operation.
Other than that possiblity it does kinda stink of a MAF sensor.
The number of fuel pumps isn't dictated so much by the engine as by the chassis. The 202's have one in-tank pump.

PS That gasket is a REAL pain to install correctly, not as bad as a 104, but close.
