Missfire @ Idle
Hey everyone maybe sombody on the board can help me out on this, let me give you some background on my S first.
She is an o1 @ 65k no major problems at all, just the tranny tsb's and high oil consumption...1 quart every 1000 miles.
She seems to misfire at idle with a put put put noise, and sometimes she bogs down hard to like 100-200 rpms after tapping the gas or pulling up in neutral? The cel came on for one day then shut off. When driving/accelerating she seems to run fine!
has anyone else experienced these symptoms?

Your symptoms can be caused by a number of problems. I had the same symptoms on my daily driver, and a new set of plug wires took care of it. But the S2000 isn't wired the same. it could be a faulty coil pack. But before you start replacing one, here are a few things you need to do:
Check to see what code the CEL was giving you. This will tell you which cylinder is a problem. Switch coil packs with another cylinder and see if the other cylinder gets the CEL.
Do a compression and leakdown test on the engine. Given that you're consuming some oil, you might have a scored cylinder. Poor compression could give you those sympoms. A leakdown will tell you if it might be in your valves.
Check your plugs. See if any of them look fouled. Swap plugs with a good cylinder. If the problem moves to that cylinder, you know it was a bad plug.
I doubt that it is your fuel injectors but if you try everything above and still have the problem, you might try some fuel injector cleaner.
