My car accelerates on its own....

Thanks for all the great tips, everyone.

Quick question...would a dirty throttle body be causing the SES light to light up?

Not Likely. best to pull the codes. Autozone will do it for free if you have one local.
I'm with Mysatilac on pulling the throttle body for a few reasons.
1 Cleanlyness, less mess in the engine bay. Not to mention the fire hazard you can get into with an oil/grease covered engine and a flammable throttle body cleaner.
2 It is almost impossible to see into the port that the IAC valve fits into without a mirror to see if it is clean. The IAC is on the fire wall side of the throttle body. Not to mention those darn small torx head screws that hold the IAC valve in the throttle body. They have a way of falling. If you are on pavement they get stuck in the car. If you are on gravel they fall thru to the ground. Either way never to be found again.
3 You can also clean the beginning of the intake manifold.

Try it your self. Only 2 fasteners hold it on. Disconnect the air cleaner hose, the vacuum lines,Pcv hose and AIC and TPS connectors. Take the fasteners off. Tilting the throttle body makes the the throttle cable a snap to remove. That's it.
Take it to the bench,remove the IAC valve (2 torx screws and DO NOT LOOSE THE O-RING, saturn oem $12.00) and remove gasket as needed.
Get your tooth brush(by yourself a new one), Some sensor safe throttle body cleaner and have at it. Some reuse the gasket but I don't.
Reinstall and u b done.

Good time to clean the EGR while your at it.
Let us know how U make out.

your kidding me, $12 for an o-ring? i thought 5 dollars for the grommit around the valve cover bolts was bad.
