Your resistance is about double what the spec given is, that CAN cause your issue since the amperage running through the pcm drivers is quite low. If you're getting spark your pcm has to be working. Just look around clean up chassis grounds and such if you're really worried about it (never a bad idea anyway). Try a trip to a salvage yard w/your meter and see if you can find a replacement for the coil pack, otherwise it sounds like its time for a new one. Plug wires should read several K ohms per foot, but ohming out wires doesn't always tell you the whole story (not any/enough current to tell you if the wire develops high resistance when it gets hot w/electricity running through it). Basically though based on your tests/info, new coil pack first, then maybe wires (should be cheaper than the dist type) and if none of that solves it, THEN look at the pcm.
