Thanks for the advice!

I hade the spark plugs replaced about 1,000 miles ago so that can't be
it. Where are the IAC and TCS located? I would like to take a look at
them and try cleaning them if they aren't hard to get to.

Was that before or after the problem started? If before, it might just be
that you got a bum plug...

You know, I always suspect the MRFWU (Most Recently F***ed With Unit)
