Engine Starts then Dies
We have a 2000 Toyota Avalon that has been running fine, until this morning. I went to start the car and it started but when I took my foot off of the accelerator it died out. I tried this again several time and again the same result. If I keep my foot on the accelerator, it keeps running and it will keep running and sounds fine. No Check Engine light is coming on. It is just when I take my foot completely off that it dies out.
Can annyone help me out on what this might be and why it is happening.
Thank you in advance for any help that you can give me on this issue, it is greatly appreciated!!

gregtech,
Thanks for the quick reply!! How would I go about finding that? If you describe what it looks like or where it might be located, it maybe I can find it. I don't really know that much about cars but I am willing to learn!!
Also, should it be tapped when the engine is running or when it is off?

it is located on the bottom of the throttle body. you probably have to take the engine cover off to see it and the throttle body is the piece that the hose from the air cleaner connects to.if this does not fix the problem have someone start the car while you have the hood open and listen for a vacuum leak,it might just be a hose that has come off.
Good luck

gregtech,
I owe you big time!!Beer 4U2 I tried the tapping method that you suggested and it worked, at least for now anyway!!
In your educated guess, will this start to occur more often now that it has happened once or will the problem be fixed for quite some time? If it continues, what will need to be replaced and will it be expensive? (I would have to take it in to a car repair place for this, since I do not know much about the engine).
Once again thank you so much for your help on this problem!! You saved me alot of grief for Monday morning that I was not looking forward to having to deal with.

I am glad that I could help,this may or may not have fixed the problem,It could have just been some carbon build up and you knocked it off,or the soleniod could be going bad. if it continues to cause a problem I suggest that you get it replaced

its pretty simple. The Idle air control valve provides a passage of air for when the throttle is suddenly closed,on the other hand the EGR valve opens when engine performance would not be compromised (decel) and exhaust gases go into the plentum chamber so when the IAC opens it suckes some of the exhaust so that is where the carbon comes from.
