Have you pulled out the spark plugs to see if there are any tell tale signs on them.They are a good indicator of many problems that occur and can save a lot of time isolating the problem.They should all be the same colour.Is the air box and lid properly secured with no leaks or splits in the intake tube.Have you put injector cleaner in the fuel tank to clear up any possible dirty injectors.Therse a few things your problem could be including engine vacuum leak which you can find by lightly spraying carburettor cleaner around suspect places such as inlet manifold and around injector seals.

If you have the 4afe engine, normally you need to check the idle control valve if it needs cleaning. Check also the timing of the car.

I have a similar problem with one of my Toyota Corollas. It's a 95 model with the 1.8L engine (7A-FE, automatic). But unlike yours, it has plenty of power while running. Here's what it does. Occasionally the engine misses. Sometimes it will die. This is most likely to happen when you start the car and put it in reverse and start rolling without giving the engine time to adjust. I've been told by some customers that it will die sometimes when coming to a stop. But this has never happened when I drive it. I don't think it's a fuel issue because the car runs just fine when it's running.

Here's what I've tried so far:

1. Replaced spark plugs and wires.
2. Used gasoline additive fuel injector cleaner.
3. Checked air filter.
4. Checked vacuum hoses for leaks.
5. Replaced PCV valve and hoses.
6. Cleaned the air intake and throttle body with carburetor cleaner.

1. Check the throttle position sensor.
2. Check the MAF sensor.
3. Adjust the idle via the set screw.

looks like yor air valve is not working properly.check the water imput (could be clogged). also,did you removed your termostat? if so,put it back and solve the problem.
