It idles fast if I turn the idle down it stalls running rich on top end at fast idle sometimes it will drop to a very low idle and shut off

hot engine or cold, or both? 180F+ is hot.
Shuts off, idling or on the fly, say at 30mph right foot down it dies?
just clue here...
engine stalls. is complex. but in the macro its below, using tools finds the reason,, but you never said did it restart easy./??????
1: lost of engine compression hot engine, (or overheated)
2: lost 12vdc electric power at stall (caused it) dash goes dead. ?
3: lost spark, test spark at the failure point. if dead trouble shoot speak.
4 bad fueling, too lean (say the fuel pump dies) or too rich.
too rich causes wet spark plug tips. (lots of causes )
5: stalls due to idle RPM too low, below 800 is too low.
too low idle rpm is caused by many things, but top 2 are.
A: EGR stuck wide open, clean it, as the books shows at 60k miles
B: ISC stuck closed. (same deal clean it)

now repost and say when it stalled,
at a read light or flying up a hill wot, wot= wide open throttle.
and when it dies, is the restart easy or hard.

There is no fixed carburetor setting on these engines, just two screws to adjust low-end and high-end operation. Special tool may be required, there are about a half-dozen screw head standards. Check eBay for tool. Get the engine to run and idle fast (idle adjust) so it doesn't stall, adjust low-end screw so that engine doesn't hesitate or sputter when accelerated. Adjust high-end screw to run fast and smooth on full throtle. Readjust idle to normal.

Get the Idle air control valve checked inspected.Also its suggested to get more troubleshooting done.For more troubleshooting,click the help,links below:---Idle Problem? http://whatisbyme.blogspot.in/2012/05/2001toyota-corolla-idle-problem.html

Do the following to clean the intake, this should help with the rich run. Also change the oil, it will be full of fuel.
Buy a can of throttle valve cleaner (it is made by CRC) from the local auto parts store, NEVER USE CARB CLEANING SPRAY, IT DESTROYS THE ANTI-STICK TEFLON COATING, spray it into the air intake through the throttle body of the engine until you have used about half the can, you will need to hold the idle up while you do this, it will try to stall, after this shut the engine down and disconnect the Negative (-) battery cable for 5 minutes. The intake is now clean, if you continue to have the idle speed control problems you may need to seek the help of a professional

it sounds like its drawing air into the inlet mannifold

The E-brake light is on because the brake is slightly on, or the fluid is low, or the brakes are failing It sounds like the fluid is getting low from normal brake wear and not a problem. Just get the front brakes cheched and replaced. Don't put any fluid in because the new brake pads which are thicker will take up the space the fluid has dropped and push the fluid back to the correct level

Your engine is shutting down at idle because of a a bad seal on the engine induction system. It is the big duct that connects to the engine air intake. Leave the car running at idle, E-Brake on, and squeeze the big black duct going from the air filter to the engine, Does the car shut off? Next check small little hoses that attache to this big air duct. Try moving them a little to see if the engine runs different.

If these are good then I would shut off engine and remove this duct. A hose clamp holds one end. A slotted srewdriver will work to remove this clamp. The other end, at the Air Filter simply unclamps by hand.

The Throttle Valve is the first thing you see in the engine, it is inside the intake just after the duct you removed between the Air Filter and Intake. Have some one open the Throttle by stepping on the gas pedal and see if it is clean around the edges. If not, use some cleanning alcohol from your medicne cabinet to clean this area. A toothbrush will get into the tight spaces. Wipe clean with paper towel. Autozones sells a special cleaner called Throttle Valve cleaner spray. Use this not Carburator Cleaner.

If it still runs bad a idle the idle valve could be dirty and now you need more tools to remove it and clean too.

Here is the most common cause of surges and stalls at stops and low erratic idle speed and rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Clean the throttle valve and the air bypass idle speed control valve, they get full of sludge and restrict air flow, this causes a low idle at times and the engine will stall, clean them by spraying carb spray into the throttle valve while the eng is running, have someone hold the idle high or it will stall, after using at least 1/2 can shut down and disconnect the battery for 5 minutes, this clears the memory and allows the computer to relearn idle strategy, the computer willl take a few days to relearn the idle, maybe 30 miles of mixed driving.

Hello two major culprits off this is your TPS sensor wich controls the idle what you need to look at is when you start the car does the Rpm needle stay in a semi fixed position give or take a couple of lines or does it idle erratic it should be at a semi fixed if erratic it probaly is out of range you can test with a ohm meter if not autozone offers free testing on sensors The second problem wich sometimes can not be detected by a scanner and doesnt always set a hard code is your IAC motor IDLE AIR CONTROL VALVE wich is inserted internal into your throttle body on the end of this has a top shaped piece wich plugs a bore hole internaly inside if this is built up with carbon or varnish it binds internally causing higher idles, lower idles ,stalling, nostarts ,hesitation,rough idle, etc this mounts with usually to torx shaped screws also can be tested with scanner but dont rule this one out it can retract and extend register fine to the computer but bind internal with out ever setting a code goodluck please rate thanks
