94 Corolla engine stops while idle

Hi, I have a 1994 Corolla with 140K miles on it.

These days, the engines quite often stops itself while the car is idle,
for example, while I am am waiting for the green light.

Luckily, right now, I can still turn the key and restart it. But I am
afraid some day, it won't restart anymore and has to be towed.

Some problems I feel about this car recently.

1. The exhaust pipe spits out some water while idle on cold mornings.

2. The car is shaky while idle. I can feel it on my seat behind the
wheel.

3. The car seems to accelerate itself, don't know if this has to do
with the low pressure of the 2 front tires. (The problem seems to be
better if pump up the 2 tires, however, I don't feel for sure.)

I just had the battery and alternator checked 2 days agao and they were
both fine.

Any idea why the engine stops itself?

Your Question

#1-- Normal

2) -- Idle speed is too low

3) -- I'm assuming your car is fuel-injected. I'm Old-School, don't
know much about that new-stuff, I'm still in the land of "dino-carb."
Nothing to do with tires.

I would recommend a basic tune-up, telling the shop that the idle is
set too low.

My guess is that it's the idle speed regulator, which either presses on
the throttle or routes air around the throttle to adjust the idle.
Look for bad electrical connections or vacuum hoses.
