I've been having sporadic problems with starting my vehicle. I will get it started and then it either idles very low or shuts off completely. When I do get it started, it runs fine. I brought it to a repair guy and he believes the problem is in a little box that lets air into it w/ a little valve (don't know the name). He believes this part has become dirty inside and says that Toyota says it cannot be cleaned - it must be replaced. What is this part, can it be cleaned and how much will it cost?

I own a 2001 Toyota Sienna, it would not stay running when at Idle. Toyota put an line from the exhaust into the throttle body to help return and burn any excess fuel originally not burned the first time thru the system. On my vehicle I have taken the hose off of the throttle body down to where this exhaust line re-enters the throttle body (right at the butter fly valve in the throttle body). I cleaned the carbon that had built up around the butter fly valve (with carburetor spray cleaner) to remove the carbon. Reassembled the disassembled componets. My vehicle then idled properly. Other wise you must keep the vehicle above an idle to keep it running. When you had to stop or slow down and the idle dropped low enough the engine would die. After cleaning it has worked fine. I hope this help other Sienna owners.
