bad carb adjustment or a dirty carb (Get a tune up or try a bottle of sea foam from your local auto store) *Some older cars with lock-up torque converters can have a failed TCC (torque converter clutch) circuit. This stalls the engine as the converter is locked solid, connecting the engine to the wheels.
A low idle speed can cause this.
outboard motor will start and idle, but dies out under load
Sounds like a motor mount or a transmission problem.......
crankshaft sensor going.
It needs adjusted it is still engaging. just like when it is running in Neutral and you put it in first gear it idles down more so than typical of a bike doesnt it ?
No, you may have to check your idle. You can change the idle so when you put it into gear it will not die. You must make sure that the engine is warm when you adjust the idle or it may make it hard to start when the engine is cold. When it idles in park or neutral it should sound a little higher than when it it idles in gear or drive or reverse.
You may have a faulty coil. Check mass air flow sensor
if you got an automatic depending on what gear it is you may need a 2800 or 3500 rpm stall in your torque converter call a transmission shop if that's it they will help you
check that choke is operating correctly
The trans won't cause it to die. Try changing the fuel filter.
If a 1989 Honda Accord is experiencing idle issues the idle air control valve should be checked. A malfunctioning valve will cause the engine to run richer to compensate for less air and cause the car to have bad fuel economy.
if the kickstand is down, the safety switch will kill motor. or it may be defected.
It is quite possible that your clutch is not disengaging the transmission from the motor. Also, your synchros could be bad, which would not allow it to go into gear.
