All:

I just recently picked up an 02 S2k with just shy of 100k miles. I am currently going through and giving it some TLC where needed.

I have the paperwork of where spark plugs were changed at 90k miles, That being said after the car is warm a I feel some increased idle vibration that I don't feel at all upon startup. Cold start-up the idle is 2000 and once warm 1000 or a little lower.

Is this normal? Aside from that no engine/shift/idle issues at all. I just didn't know if it normally idle's like this.

I checked around the site and have no stall or CEL issues but wanted to throw the question out to the forum.

That's perfectly normal mate, mine does that, they all do that

Forziii

Yeah, they all do this.
Check the IAC is clean. If it's dirty, it might be adding to this, but I think even if it's 100% clean, you'll still get a bit of vibration.
