      First step, check the engine oil level and refill as necessary. Once the engine oil level is OK, check the following items; oil filter (make sure there is an anti-drain back valve built in), check the valves/camshaft/ timing chain or belt (upper engine) for excess play/wear.

      Not much else to suggest - given the limited details provided. One other suggestion, check the noise location using a mechanics stethoscope.

    I need to replace the catalytic converter and the car is from Calf. and now in Washington St. Can I use a 49 state cat?
    Is there any difference in the rest of the equipment?
     
    • Jimm

      Purchase the converter legal for the state the vehicle is operated in; if Washington - then the 48 states model is correct.
      Check the various on-line vendors; www.autopartswarehouse.com, www.RockAuto.com, www.partsgeek.com, to list only a few. In fact, they (RockAuto) list the catalytic converter from around $318.00 for your vehicle.

      First step - have the stored fault codes or check engine light scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply as 'add answer' with the specific code for more assistance. There may be a fault code stored in the OBD memory which may not be displayed as a check engine light.

      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

    Car makes low pitched rumbling burping sound on start. Only heard on start and car seems to run fine. Any ideas?…
    It sounds like it's coming from underneath or in back. Could it be water in the exhaust-muffler that shouldn't be there?

    Flashing engine light,today.This light has been on along with the VSC light for several years.
    There were no problems driving the vehicle when the engine light was on for all these years.Neither did I feel any problem driving it for 3 miles after it started to flash.
