Correct cold start idle speed for a 1996 Bonneville SE

Can someone look at their cold star idle speed for me next time they start up.

My 96 SE recently started to rev about 2k on initial start up and I am puzzled why.
All sensors and throttle plate were cleaned when I did the intake gaskets in March.

Maybe the TPS is going out? Or injector leaking?

Idle comes down to normal almost immediately, but acts
like you are holding the pedal 1/4 way down on start up.....Weird.

1200 here. Returns to just under 1000 at 2 minutes.

Took a second look, its doing 1500 at cold start up then goes down from there.

Just sounds like it races, maybe its normal.
