Car stalls but easily restart when applying small pressure to gas pedal. also has problum holding start when key ignition is applied only must use gas pedal to start must keep pressure on peadl to remain started if not the car will cut off this only happends every so often starting on stalling problems while driving strong smell of gas

i would check fuel pressure key on engine off should be around 40 psi if thats good it sounds like bad IAC valve idle air control valve

If you a mechanic friend, ask to check the fuel pressure. It will tell you what is wrong.

You may need to reset the system.

SEQUENCE ACTIVATED BY THE PARKING BRAKE .
1. While engine is running (key in ignition switch), apply the brakes and hold the pedal down.
2. Move gearshift lever to neutral.
3. Apply the parking brake Once Twice
Note: The system can be set - at time of installation - to require that the parking brake be applied once or twice.
If set for two actuations, pause one second between the two.
4. Remove key from ignition (the system keeps the engine running).
5. Exit the vehicle.
6. Within 60 seconds, close all doors.
7. The system will stop the engine and blink the parking brakes once to confirm the sequence is valid (vehicle is
ready for a remote start command).
SEQUENCE ACTIVATED BY THE REMOTE CONTROL

5. Remove key from ignition (the system keeps the engine running).
6. Exit the vehicle.

Fuel pressure or delivery or blown head gasket or bad compression. There are no service lights on?

change the fuel filter and make to clean the fuel inectors

This will depend on how much of the key is left. You could try this:

WARNING: This could cause a worse problem

This assumes that you have the part of the key that is not stuck in the ignition. If the car is not already in "park", turn it to the park position.

Get a tube of superglue and apply a very small amount along the part of the key where it broke off. Try not to get any on the sides of the key. You only want it on the "break line". (If you get too much on, let it dry and then peel it off with a knife or other tool and start over. Don't try to wipe off exess with a cloth or paper, it will just make a mess.)

Immediately after applying the glue, hold the steering wheel hard to the right or left, and then push the key in as far as it will go and hold it as still as you can for about two minutes. Next, start rocking the steering wheel gently back and forth. If the key is stuck in the "Park" position, the steering wheel will only move a little bit.

After you determine how far back and forth you can move the steering wheel, try to hold it the middle and then gently try to extract the key. If the key will not come out easily with gentle pressure, try rocking the steering wheel while you gently pull on the key.

Good Luck

these cars are carburated motors and need around 10 minutes to warm up because they operate at higher temperatures.
