Idle problems

About October of last year my '99 rodeo would crank, drop down to ~200 RPMs and then go dead. It did this for about 1 week then the opposite, it would crank at 3K RPMs and when I would pull out of my garage it would bark the tires. (My neighbors thought i was always in a hurry.) After 2 weeks of this an error light came on so I took it to the dealer. (the last time i had a problem they said they couldn't work on it if it didn't have an error light. i fix computer and wish i could give that lame excuse. "my computer won't turn on"... "is there an error light"... "no"... "sorry I can't fix it") Anyway, ~$600 later it was 'fixed'. They replaced an air censor, something, and a valve something. The valve was under warranty. 4 months after it was 'fixed' it's doing the same thing again.

Does anybody know what could be causing this? I can think of 2 things: the computer needs reprogramming or if there is something that controls the idle position if the computer doesn't.

Could be a bad intake manifold gasket.
