Two cylinders instead of four? **Resolved**

- Accels were Houdini's second choice, made because MSDs weren't readily available

Hmmm, have you tried Summit or ebay? Lots avalible

Apparently, they weren't readily available to Houdini at the time he needed them. I have two waiting for me at AJUSA.com, who are based about 5 miles from my house. More to come!

I think you will like them. I could be crazy but it feels smoother or a least I want it to feel smoother

Nope - if I was way ahead of you, I'd have figured this out from the logs instead of all that tedious mucking about with sparkplugs and wires.

I studied the logs but clearly don't know what to look for. How did you come to this conclusion? What entry in which log was the giveaway?

Gregory (Scotland Yard detective): "Is there any other point to which you would wish to draw my attention?"
Holmes: "To the curious incident of the dog in the night-time."
Gregory: "The dog did nothing in the night-time."
Holmes: "That was the curious incident."

The thing that pointed me to the coil was that there was nothing of note in the log apart from an oscillating lambda reading (probably a result rather than a cause of the misfire). Given that the coil is the most common cause of a misfire (years of being a member of LEC gives you an insight into what the common problems are), the fact two cylinders were involved and each coil supplies two plugs I thought it the most likely diagnosis. The injector circuits also run pairs of cylinders but they are less likely to go wrong.

MSD coil packs did the trick, so one of the Accel units failed prematurely. This is one time when red is definitely better than yellow. Of course, if someone made BRG coil packs, the car would gain 30HP immediately.

Fantastic! Glad that worked out!
