    Why does my vehicle sputter when taking off from a stopped position. Then is runs fine.
    I have 80,000 miles on my Kia but for the last 2 days when I take off it feels like it is not getting enough gas to keep it from sputtering at first. Then it stops and runs fine. It does not do it if I begin moving very slowly.

      First step - have the check engine light or stored fault codes scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply as 'add answer' with the specific fault code for more assistance.

      Possible Causes of Engine Hesitation or Stumble:

      Dirty fuel injectors (cleaning the injectors often fixes this)
      Dirty air filter (change filter)
      Dirty / clogged fuel filter (change filter)
      Bad MAP (manifold absolute pressure) sensor
      Bad TPS (throttle position) sensor
      Bad or dirty MAF (mass airflow) sensor
      Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
      Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
      Bad gasoline (fuel contaminated with water or too much alcohol)

      Sometimes, what feels like a hesitation is actually ignition misfire rather than lean misfire. The causes of ignition misfire may include:

      Dirty or worn spark plugs
      Bad plug wires
      Weak ignition coil
      Wet plug wires

      In almost all cases, if the battery light is illuminated with the engine running, the alternator is junk. There are some exceptions but few. The light cannot be on with the engine running. When the light is on it means the alternator is not charging the battery.

    Check engine light code 0320, 2005 Kia optima?
    Rough idle and tachometer fluctuates or drops to zero.

      P0320 = Ignition/Distributor Engine Speed Input Circuit Malfunction
      First check the 20 amp ECU fuse in the under hood fuse box. Also check the O2 sensor fuses. If good, next check for battery voltage on the tan/black wires going to the coils while cranking. If good, check for ground of 0.05 volts on the black wires going to coils while cranking. If either is missing, check O2 wires for chafing or rub thru on heatshields or other objects under vehicle. Verify the O2 sensors operation is correct, if so - suspect the ignition failure sensor.

      P0300 = Random/Multiple Cylinder Misfire Detected

      A P0300 diagnostic code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring. A P0302 code, for example, would tell you cylinder number two is misfiring. Unfortunately, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-firing, nor why.

      Causes

      A code P0300 may mean that one or more of the following has happened:
      •Faulty spark plugs or wires
      •Faulty coil (pack)
      •Faulty oxygen sensor(s)
      •Faulty fuel injector(s)
      •Burned exhaust valve
      •Faulty catalytic converter(s)
      •Stuck/blocked EGR valve / passages
      •Faulty camshaft position sensor
      •Defective computer

      Possible Solutions

      If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.

      If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

    How can I get my 2002 Kia Rio OCB-II O2 monitor to finish resetting? It is "not ready" after weeks & 100s of miles?
    Cleared a code (for very small evap system leak) back in Dec. Three monitors are still "not ready/incomplete". I have been told that the other two won't finish until after the O2 monitor does.

    My car randomly died and I've had to jump start it twice now, I thought it was fine since it was fine for a little bit after it was jumped but it happened again. It doesn't make that clicking sound when it's dead and I turn the key, so I don't know if it's the ...

      first take the battery to any auto parts and have it test, it's free, after that if your car start and do the same than you may need the alternator, but here little tip may help you,, start you car and turn on the headlight and all accessories if the light goes dim or the car stall you need the alternator.

      Try the many on-line auto parts sources, such as; www.autopartswarehouse.com or www.rockauto.com for the replacement parts.
      They (Rock Auto) list the timing kit for around $44.00 (without water pump). The water pump is around $19.00 (includes gasket) for your vehicle. Figure on around $150.00 - $200.00 labor charge over the initial parts cost.

    What is most likely causing a blinking check engine light, rough engine at low RPM and P0300, 301 & 302 codes?
    It has a new battery and spark plugs. It started with the check engine light NOT blinking and P0304 code. I pulled the battery cable to reset the computer and realized a bad battery so I replaced it. The car ran fine for a couple days, then the blinking CEL and ...

      Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open.
      Check for any air leaks around the intake.

      The P0301 - P0302 codes target the # 1 and # 2 cylinders specifically - same issues to address.
