It stalls even when warm
Depends on the code. Get it checked.
Rule of thumb: Open needle valve 1-1/2 turns and start the engine, let it warm up then slowly rotate needle valve clockwise until engine wants to stall then rotate needle valve counterclockwise until engine wants to stall. Set the valve in between the two extremes and fine tune from there for best setting.
a stall will not engage trans until a minimum rpm is reach depending on rpm range of the stall converter
That engine has 2 of them and there both are underneith the intake manifold. You can not see are get to them until you remove the intake.
That means the torque converter will not start pulling until the engine reaches 2800 RPMS. Nother words transmission will not start pulling.
A vacuum leak would do that. Check the base gasket under the throttle body.
They had carburetors back in the days of old (pre-1980's). If they weren't adjusted just right or operating properly they ran rough until the engine warmed up.
Yes it could. Why not replace it? It's cheap and most people never do until they stall some dark lonely night. It depends on what kind of car and what engine you have. Go ahead and replace the fuel filter although I don't think it will cure the rough idle. If you have a carburetor, it may need cleaning or adjusting. If you have fuel injection, try some injector cleaner in the tank.
Yes. Cam sensor will determine the rotation of the camshaft, and if it does not sense it 'turning' the sensor will not allow the engine to start (it protects damaging the engine). Faulty camshaft or crankshaft sensors will stall engine and prevent restart until replaced.
This particular model and year had problems with the lock-up torque converter solenoid going bad. The engine will stall as soon as you stop or put it in gear. If this is what is happening, disconnect the solenoid until you can get it repaired. The engine will run at a slightly higher rpm and will use more fuel, but otherwise it will do no harm for the time being, until you can have it repaired.
"They" do not cause any engine operation they are only a sensor. If they are faulty they will give a false signal to the main ECU. The engine will still operate safely until they are repaired.
when kick down the gas pedal to accelerate, the car downshift but then stalls and then engine stays rough until i turn off the engine and restart it then the engine runs normal again till the next kick down.
