Yea Rob, this whole thing is baffling me. I'm gonna pop the valve covers off this weekend and check out the valve train. Pretty sure the cam is fine though because the problem is so intermittent. Plus, I just changed the oil a few weeks ago and the oil looked fine. Either way, valve covers are coming off this weekend.
I'm still not understanding why the there is a voltage drop when it pops. Is this common??? I've never seen this before. Maybe it's a clue...
