Another update.... after going inside for a little bit to cool off, i did some more searching on this site, and found some people who had this problem fixed it by replacing the MAP sensor.

So i went outside and probed the sensor like what the Haynes manual says... it checks out at 4.97V to the connector when it is unplugged, ignition in "on" but not started. When i backprobe the connector like the book says, i read 2.88V.

But when i start the car, and read the voltage at this connector, the voltage does not increase with more throttle... While the engine is surging up and down, the voltage goes between 1.9 or so, down to .9V, and when i open the throttle with my hand, voltage goes to .9 or so and does not increase with throttle.

Finally, while the car was running and still surging, i unplugged the MAP sensor connector, and the car stumbled like it wanted to die, but then started idling normally, with no surging or bouncing up and down, as if the car was running like it was supposed to.

Does this sound like a bad MAP sensor? If so, will replacing this solve the up and down, bouncing idle problem? PLease let this be it so i dont need to take it in to the dealer!!!

And oh yeah, while i was at it i took gulf's suggestion and took the EGR valve off and cleaned the carbon out of it and reinstalled it. looked clean, but did not solve the problem...

Sorry for the long posts, and thanks again for the replies!!!
