Default High rev on startup?

In the last week or so ive noticed the vette's been revving up occaisonally on startup. Every time its been at night and i haven't been able to see how high the revs are going(ill turn the lights on next).. but ill say 1500-2000 range.

I haven't touched the TB or anything like that. Mods are in sig. ANy ideas?

I like to use alcohol on some Q-Tips, being very very careful of course. If you do decide to do some spraying, I would definitely remove the MAF first and be careful how close you get your spray nozzle to the
little thermistors in the MAF. They are spot welded into position with some pretty tiny wires and no sense putting too much pressure on them. If you do decide to do some spraying into the throttle body, don't use brake cleaner. If there are any coatings used during the manufacturing of it, it will remove them. Get any one of the products labeled "throttle body cleaner". They cost about the same.
HTH,
Robert
