My car will die when I stop at a light or drive slowly for less than a mile without any warning. The battery discharge light, the engine check, the oil pressure and the back door light will then be on. If I immediately try to restart, it won't work. However, if I wait a few minutes, restart again, it will be fine. I've sent it to the repair store several times, they have no clue. They say the car doesn't act up before them and runs fine in the store. It has about 99 k miles, timing belt changed last year, new spark plugs, new battery. The battery and alternator are tested to be fine. The battery terminals are changed. The wires and connections seem to be fine according to the store.
Something I notice is this usually happens the next day after a night rain or some temperature change, more often with warm temperature.
Today, I notice the engine coolant level is kind of low. But the car didn't die today and it is very cold.
This is getting my nerve. Please help. Thank you.

. Install a new OEM coil.

. Install new spark plugs (NGK only), if they have not been changed in the last three years.

. Install a new OEM Ignition Control Module (ICM), if the problem persists.

Thanks for answering me. I usually don't do any work myself on my car. I've been going to a Midas store for a long time. Is it OK (appropriate) to just ask them to do what you said? I thought those people in the Midas should have known better and I shouldn't give them directions or suggestions.

I'd take it to Toyota. I would not take it to Midas.

I took it to a local repair shop (no toyota dealer nearby). They first tried the distributor, the problem persisted. Then they replaced something called ignition module. Didn't solve it. Then some sensor. Still not solved.

The car is fine when it is cold and dry. When it is warm and humid, it will cut off shortly after you start. Some times within a mile, it will quit a few times. The first light coming on seems to be the battery light.

Additional thoughts:

. Test the charging system:

Particularly, focus on the regulated battery voltage. The brushes may also be worn too far down.

. Check/replace the Engine Coolant Temperature (ECT) Sensor, which affects fuel injector pulse width. The ECT Sensor is a temperature dependent resistor (thermistor), whose resistance decreases as the engine coolant temperature increases. It provides a richer mixture when cold, leaner mixture when hot. They become corroded, due to not changing the coolant frequently enough, flood the engine, and waste a tremendous amount of fuel.

Did you ever get this fixed? Mine is doing the same thing...

Thanks
