Not knowing what car it is ... a place to start is the vacuum fuel pressure regulator. Have someone hold the gas pedal and keep it at about 2500 rpm and look for leaks. Won't hurt to check the fuel pump pressure too.

Sounds like you have a either a vacuum leak or a cracked fuel line allowing extra air to be sucked into the carb fuel mixture. Make sure all small to medium sized hoses are well attached to their fittings and do not have any cracks in them.

SOURCE: engine revs remain high or increase when braking

Have you tried checking your throttle positioning sensor. Possible vacuum leak or check for carbon build up in the throttle body not letting the throttle valve shut all the way.

This is not a rich mans car so its normal. Your hearing the solinod that lets you take the car out of park after the brake is depressed so the car can't be put in gear unless the brake is on. If the noise bothers you the soliniod can be found and wrapped in insulation like a rich mans car them you can ride on feeling like a rich man too. ( the Beatles sang that a long time ago) and its still true today.

Have to press gas pedal to get engine to turn over


Pedal pressing has nothing to do with it. You problably have a bad starter or battery. Check your connections too.

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
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 parking brake.
4. Send the start command (Model 801 & 2101 - Model 903 ).
5. Remove key from ignition (the system keeps the engine running).
6. Exit the vehicle.
7. Using the remote, send the STOP command. The system will stop the engine and parking lights will blink once
to confirm that the sequence is valid (vehicle is ready for a remote start command).

When I first try to start the car, ignition only, no gas pedal, the car will run then stall. This will happen multiple times until I apply full gas pedal and race the engine. Radio will get louder and...


Problem with idle control valve, is located underneath throttle body, you can clean the valve, but there is 50 50 chances that is going to help also may get worst, I would recommend replacement.

Key broke inside the ignition


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.
