Fuel pump

Check the idle position sensor.

Have the catalytic converter checked at your local muffler shop...clogged...worn out...Hope this helps.

It sounds like the catalytic converter could possibly be almost completely plugged up not allowing the exhaust to leave the engine like it should. It just builds up in the cylinder head and when it gets too much in it built up and there's no where to go, it'll stall the engine. By letting it sit for a few minutes, it gives the exhaust time to find a way out and the car will restart.

WELL IF CAR WAS 5 QUARTS LOW YOUR PISTON RINGS AND CYLINDERS WALLS DAMAGED ALSO CRANKSHAFT BEARINGS AND ROD BEARINGS SEIZED.DO A COMPRESSION CHECK.IF ENGINE MISSING LOW COMPRESSION CAUSED BY DAMAGED PISTON RINGS AND CYLINDER WALLS BECAUSE LACK OF OIL.

Petrol pump or filter, Say Please ......

My 97 CAmry was stalling at idle. Sometimes at stoplights or even when comming to a stop. Ran fine most of the time except at idle. It would shut off like i turned off the key. Found out the coolant sensor was shorting out intermitinly..Disconnect the sensor and sending unit if not sure which is which. The check enginr light will come on but that could be the stalling problem.

It doesn't have spark? Or you don't Know? Did you check fuel pressure?

Sounds like your IAC motor is getting stopped up. Clean out the passage, and the throttle body. If that doesn't work, get a new IAC motor.

try checking the coil igniter, if this is faulty and it gets hot it will really make your car die but when its cold it will make your car run again.
