Re: 2 days ago, only 1 cylinder firing, yesterday BOTH, today just 1 again.

Well, I have checked all the wiring, everything checks out fine. The other day, I swapped coils around with some rigging, and the problem moved with the coil. But before I take that plunge ($300 for the OEM for the pair, or $150 aftermarket from Dennis Kirk), I am going to try different plugs. I have brand new NGK's in it, but I have seen all the posts on here about using Autolites with much better results, which goes against everything I learned in auto mechanics. But, worth a try.
