dd
99 jeep Cherokee Laredo stay running after turn off the ignition switch?
my 1994 jeep larado turns over then dies out
Its out of gas
lack of fuel
check ignition
If it will shift when the engine is off, but not while it is running your clutch is not working
to me it sounds like your map sensor is going out, you might want to check that.
weak fuel pump.
the panic alarm is a part of the anti-theft system. The computer knows that a part of the system is not working correctly, and won't let the vehicle stay running. hope it helps. duboff
you have a cracked distribtor cap
dirty carb bowl or water in the carb
