Bank one fuel system lean. Test fuel pressure, check for vacuum leaks,
check your timing and vacuum advance and vacuum leaks. from there check fuel delivery system.
It is computer controlled and is not adjustable.If idle speed is incorrect, you will need to check for vacuum leaks, inaccurate sensors, or a failing idle airflow control motor.It is computer controlled and is not adjustable.If idle speed is incorrect, you will need to check for vacuum leaks, inaccurate sensors, or a failing idle airflow control motor.
Check for vacuum leaks.
check your water pump
allot of reasons check the carb. check for vacuum leaks. check the timing. check the comp codes.
Technically, a diesel engine does not need any outside electrical source to keep it running. Injectors are mechanical and keep running until they are forced off, usually by a solenoid. Check the shutoff mechanism to make sure it isn't sticking. This diesel shuts off using vacuum. If your vacuum is low or leaking, the vehicle will not shut off using the key. You have to open the hood and push the SHUT OFF plate near the top of the engine in the fuel linkage. Vacuum leaks are common and will keep the door locks, climate control, and engine shut off from working. The shut off valve, located on the back of the injection pump, can fail. It is vacuum operated and the diaphragm can tear. Vacuum test this valve. If it holds vacuum keep looking for other vacuum leaks, if it leaks replace it.
Assuming it's a gas, not a diesel....these are the really easy things to do: First check the ignition system, making sure the plugs and wires are good, cap, too. Second, listen for any vacuum leaks. Third, change the fuel filter. If it's a diesel, you may have some serious fuel pump issues.
check for vacuum leaks, broken hoses and hisses.
