I have a 2003 Solara and when I move the selector switch

Customer Question

I have a 2003 Solara and when I move the selector switch from off to any position the car dies. It is a 4 cylinder engine. I think it may be a vacuum leak in the selector switch or elsewhere in the vacuum controls.
JA: How old are the hoses? And what driving conditions do you most often encounter?
Customer: Original. The car is mainly used as a commuter with about 15 miles each way to work. The cold and wet morning here in Washington make it difficult at best to keep the windshield clear.
JA: Are you fixing your Solara yourself? What have you tried so far?
Customer: I will be trying to fix myself. I haven't tried much yet, more looking on line to narrow my search.
JA: Anything else you want the mechanic to know before I connect you?
Customer: I will be taking the car across country in the near future and really need to get this issue resolved. My other problem is I have a very limited budget and taking it to a shop is beyond what I can currently afford.

At idle with the air off where are your rpms at?

Expert:  Ivan Alvarez replied 8 months ago.

If the rpms are to low at idle and you add another load such as heater/a/c system it can the car to stall. The first thing you need to check for is a dirty throttle plate. You will have to remove the air intake tube off the throttle body to visually inspect throttle plate. If its dirty clean it with a rag and solvent like brake clean or throttle body cleaner. Spray the cleaner on the rag and open throttle to clean the plate and bore as best you can. After doing this it should raise your idle and you can see if this resolved your issue. Let me know how it goes.
