Throttle Actuator

Well I have been having this problem for a long time now, and I'm sure this has happened many of times with this car.
MY car does not want to start every time I try. Sometimes it will seem to start but the gas never kicks in. Then if I try it and put my foot on the gas, it will start. It only does this when I try to start my car. It never stalls once it is going. I took it to a shop and they said the throttle actuator is the problem and it would cost $564.00.
Does anyone have any experience with this? The tech told me this part was hard to find but he found one. I also know they will try to sell you new parts even if its just a minor thing that can be fixed.
Any help would be greatly appreciated.

Thanks
Chris

what year is your car? 2004 up with electronic throttle drive by wire id assume. You can look im sure someone will sell you one used for alot cheaper then that.

ooops

I guess I can try craigslist or something.

is that supercharged or not? SE is not i think.

well thanks.. cleaning the throttle body seems to have worked.. i went to a mechanic...but they charged me 50 bucks ... 40 labor and 10 for the cleaner.. I know it would cost me like 3 bucks if I knew what I was doing.. Im buying a manual to learn on my own.

It's easy. Take off the intake tube, push throttle plate open. Clean. Turn the key to on, wait a few seconds, go back to off, repeate a few more times (relearns the throttle plate position). Should be like new.
