Default 97 XLE dies idling after driving for short period of time

Hi guys. I hope I am not the only one who had this problem so first,
sorry about asking the same question and second, please redirect me to
the right post if any (I don't seem to be able to find a match).

Here is the situation. My car starts and runs great - hot or cold.
However after I drive it for 5 mins (never checked exact timing and
perhaps it varies slightly), when I stop on lights, it basically
looses reves, starts shaking and dies. At some point I realized that
if I put it in neutral and give it some gas (like up to red sector),
the problem goes away and it would idle normally.

So what can it be? Gas pump? Some sensor?

Thanks,

DS

How many miles? In California or outside CA?

Just a hunch - try changing the Engine Coolant Temperature (ECT)
sensor (about $30 at Napa Auto Parts) and let us know what happens.

This sounds so promising. Thanks for point to this. I'll do it and
report what happened. And it is 150K miles.

Make sure you change the real ECT sensor, not the ECT sender (which
just goes to the dashboard temperature gauge).

The real ECT sensor is bigger - I think it has 2 pins on the bottom,
if the '97 is anything like my '96. The ECT sender has only one pin
on the bottom.

I confused the ECT sender with the ECT sensor, and suffered the
stalling for about another year after until I discovered my mistake...

Best wishes,

Michael

Thank you for the hint. BTW, I have no idea where it is located.

The engine coolant temperature sensor is a 2-wire deal, not the 1-wire
thing for the instrument gauge.

This sensor is typically on the coolant outlet area of the engine. On
the V6 you should be able to find it near the radiator cap. On the I4
you should be able to find it on the outlet pipe. Both are near the
upper radiator hose, engine side, of course.

The free repair guide on Autozone only shows the I4 one only. if you
put an ohmmeter on it, it should be about 1-1.2Kohm around 50-60degF
down to nearly 0 at operating temperature.

Also, check the idle air control (IAC) valve. Many of these often
stick, and can cause the problem you described. Google the notorious
"Toyota IAC valve cleaning"

If both the temperature sensor and IAC worked out, then check the EGR
valve, it may stick open. This can be checked by a vacuum gauge to the
hose at the EGR valve. It should measure 0 vacuum at idle.

Autozone has free loaner tools, including Mity Vac vacuum pump/gauge.
Of course, if you do need a temp sensor, they'd like you to buy it
from them.

Hi guys. I have installed the sensor and the car appears running fine
now. Although I made just one usual trip, it used to stall on the way.
Today it didn't. So thank you very much for your help. Really
appreciate that. Previous owner tried to clean injectors and gas pump.
But apparently it was waste of money. I spent 40 bucks and 5 mins of
time. Awesome!
