Take the car to a local Auto Parts Retailer, and have them check the fault codes on your on-board computer. Given the year of your car, it is probably an OBD-2 type computer. They can print out whatever the computer diagnostic says the problem is. I am going to guess the throttle position sensor is to blame since it sounds just like what my sister's Mazda Mommyvan was doing.

2003 Toyota Avalon xls model all lights and dials on instrument panel go off and engine stops when I go over bumps. I wait 2 minutes and car starts up again and runs fine until I go over bumps again.

The very first thing I would check would be if the battery cables are clean and tight. After that I'd lean towards a bad ignition switch. Do you have a ton of keys on your keyring? wiggle your key while its on to see if you can recreate the problem.

I have a 2003 Toyota Avalon. My toyota problem is the check engine light that came on.

Hello. Welcome to FixYa. Please allow me to assist you. The Check Engine light comes on for many, many different reasons. The most common reason is the gas cap being loose. I would check the cap for being loose. If it is loose, drive the car for 10-15 miles to see if the light goes out. If the cap is not loose, you should go and take the car to someplace that can scan the car's computer to get the codes, the reason for the light being on. Autozone stores do this for free. Get us the codes, and then we can isolate your problem better.

2003 Toyota Camry 166000 mi., 2.4 liter 4 cylinder. ONLY WHEN CAR IS HOT, idle drops off, engine stalls, must step on accelerator to keep from stalling. Otherwise, idles normally. New spark plugs,...

Some "check engine" light in your dashboard? If YES, need to scanned the PCM (computer) to know exactly what fault code is stored there. If NO, the crankshaft position sensor may fail, causing engine stalling or a failure to start. Replacement or the failed sensor will commonly correct this problem.

Also, keep in mind that on the 2.7L V6 and 2.4L 4 cylinder, a defective Exhaust Gas Recirculation (EGR) switching valve may cause an intermittent rough or unstable idle engine.

Stalling synthoms... you can have a plugged exhaust, plugged fuel filter, bad airflow meter, problem with the ignition system, incorrect timing belt/chain setting, and failing fuel pump....I'm sure there's more but that should get you thinking.

Keep us updated.

2000 Toyota Avalon stalls when foot is not on gas pedal. Any ideas. I put it neutral at red lights and pop back into drive when light turns green.

Sounds like the IAC valve is carboned up. This valve can usually be removed easily with 1 connector and 2 bolts. It is how the engine controls the idle speed. Many times a can of carb cleaner and working the piston back and forth on it will free it up for many more miles.
Turn on the a/c at idle. does the idle speed change?

Idle too low on hot starts 2001 Avalon

Sounds like you idle air control valve is going bad. They start acting up on a hot engine due to sticking or high resistance through its internal windings. It will get to the point where the engine will stall every time you take your foot off the gas.
I suggest getting it replaced and the throttle body cleaned at the same time since it will need to be removed to replace the IAC.

Don't take a chance on what the dealer says, when the engine light comes on take it and have the code read and it will tell you what is going on. The light must be on at the time the code is read though or it won't tell you anything. Most auto parts stores will do it for free.
