My GS makes a noise. It doesn't bother me, but I'm curious what it is.

1) It only occurs within the first 30 seconds of turning on the engine.
2) It can happen a few times, or none.
3) I hear a distinct CLICK from the engine, then the RPMs sag a bit then return to normal.


Any ideas?

I sometimes have the same symptoms with my '97GS....

You're prolly having a misfire. Maybe mix more than likely, maybe sucking air maybe exhaust leak. When hot its all seals up nice and good. The opposite of electrical sheite where when it gets hot its all goes to sheite.
Cool.

+1 misfire.  I get them on cold days every now and then.
