Default RPMs drop then rise to normal idle after starting

I've got a 99 SC2 AT and whenever I start it the RPMs drop to 500 or so for a second or so like it's going to stall, but it never does. The RPMs then go back to normal. The plugs and wires were replaced a few mothns back, the TB and EGR are clean. Any ideas on what to look at?

REWARD EXCELLENCE!

Default Re: RPMs drop then rise to normal idle after starting

My 97 SL2 does this as well, when I start it (after it's been sitting for awhile, like overnight) it feels like it's going to stall right before going to normal.

I would be interested in any ideas on why this happens. I, too, have new-ish spark plugs, wires, and ECTS
