Add me to the list of those that was having the stalling out problem with their car. I did all the precautions that some of you had suggested, i.e. took off the throttle body & cleaned it, checked for leaks, etc. Nothing was fixing the problem.

Finally called the dealer yesterday (Sat.) to order a new TPS. Luckily they had 1 left in stock, so I bought it ($78.33) and came home to install it.

That was the fix. Car is now idling normal. No more surging or falling below 750 rpms.

Thanks to forums like this and its members.
It saved me big $$ not having to take the car to the dealer.
