There are several potential causes for a car stalling at low RPMs in gear, and a vacuum hose problem is one possibility. Here are some other things to consider:

Fuel delivery issue: If the car is not getting enough fuel, it may stall at low RPMs. This could be due to a faulty fuel pump, a clogged fuel filter, or a problem with the fuel pressure regulator.

Ignition problem: If the car is not receiving sufficient spark at the spark plugs, it may stall at low RPMs. This could be caused by a faulty ignition system, such as a failing ignition coil or a damaged spark plug wire.

Clogged air filter: If the air filter is clogged, it can restrict the flow of air to the engine, which can cause the car to stall at low RPMs.

Throttle body issue: If the throttle body is dirty or malfunctioning, it can cause the car to stall at low RPMs.

Mass airflow sensor problem: The mass airflow sensor measures the amount of air entering the engine and sends this information to the engine control unit (ECU). If the sensor is not working properly, it can cause the car to stall at low RPMs.

To determine the cause of the problem, you may need to have the car inspected by a mechanic. They will be able to diagnose the issue and recommend the appropriate repair. In the case of a vacuum hose problem, the mechanic will check for any leaks or damage to the hose and replace it if necessary.

Try going to a higher octane fuel ie 95 or 98 .If that works !
THE PROBLEM IS WITH THE UNIT THAT ANALISE the EXHAUST GAS .Can be oxcidated .

1) Turn on all electric systems- AC/wipers/radio/lights etc

2) if car stalls randomly at low RPM - Replace the Alternator
These cars are very sensitive to fluctuations in voltage and it will stall.

Considering that it occurs more often with the a/c on, it is most likely a problem with either your battery, where it is too weak to sustain the engine output, or with your alternator. I advise checking your battery, and if that isn't the problem, checking your alternator. If neither of those seem to be the problem, its also possible that it is your torque converter, or a skewed setting in your ecu, both of which would most likely need to be checked by a professional.

it sounds like the fuel pump is going out, and it sounds like the switch in the door is sticking. you can try to spray a contact cleaner, this may help, but I am sure if you bought a new switch it would fix the problem. Hope this helped tim

We would need to konw the codes to be able to answer that .

sounds like your carb is getting to much air some where check your hoses

These re known for head gasket failures when at operating temp. should do a compression check hot and cold.

The CAMshaft position sensor is faulty.

check fuel pressure regulator.+ vacuum lines going to it look see if gas in vacuum line.if so regulator rupture.
