Default Re: RPM jumps up and down when starting

I would clean the Throttle body, if that doesn’t work maybe replace the TPS sensor?

My Saturn had a similar problem, but would rev to 2000rpm and not go down at all ( when first turned on). I replaced the TPS sensor, pulling one from the junkyard, and it has worked well for over a year.
