    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?

      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?

    When the dipstick is pulled with the engine running, the idle rpm drops. What could cause this?
    4 cylinder naturally aspirated gas engine.

      Check your pcv system. Crankcase ventilation should be a closed system. When you pull the dip stick your creating a vacuum leak, that can effect your idle.

      A faulty gasket can also cause a vacuum leak.

    Why does my car hesitate, buck and have a large decrease in fuel mileage?
    New spark plugs, wires and ignition coils. EGR new. Mass air sensor new. The engine runs smoothly at idle and when revved. Symptoms are fairly frequent when driving.

      The check engine light doesn't have to be ON to store a fault code.DO NOT SKIP THIS TEST.

      Check the vehicle for fault codes to see if there are any sensors were involved to the malfunction of the engine.

      1.Local auto parts stores such as Autozone ( not in California) or Advance Auto parts or Pep Boys will scan and retrieve any diagnostic trouble codes ( dtc ) stored in the powertrain control module for free of charge..

      2. Amazon.com has the code reader for less than $ 18.49 dollars + shipping
      Autel MaxiScan MS300 CAN Diagnostic Scan Tool for OBDII Vehicles

      3.Re-post the dtc's in here " answer question " for further assistance.

      Note: we need the dtc's to identify the sensor, there are a dozen different ELECTRONIC sensors to operate the car.

      Visit this site and see all the different sensor definitions.

      Powertrain Control Module (PCM)
      Throttle Position (TP) sensor
      Mass Air Flow (MAF) sensor
      Intake Air Temperature (IAT) sensor
      Idle Air Control (IAC) valve
      Engine Coolant Temperature (ECT)
      Heated Oxygen Sensor (HO2S)
      Camshaft Position (CMP) sensor
      Knock Sensor (KS)
      Vehicle Speed Sensor (VSS)
      Crankshaft Position (CKP) sensor

      Sorry it took this long; but here are the Toyota codes:
      P1130 - Air/Fuel Sensor Circuit Range/Performance (Bank 1 Sensor 1)

      P1133 - Air/Fuel Sensor Circuit Response (Bank 1 Sensor 1)
      
P1135 - Air/Fuel Sensor Heater Circuit Response (Bank 1 Sensor 1)

      P1150 - Air/Fuel Sensor Circuit Range/Performance (Bank 1 Sensor 2)
      
P1153 - Air/Fuel Sensor Circuit Response (Bank 1 Sensor 2)

      P1155 - Air/Fuel Sensor Heater Circuit (Bank 1 Sensor 2)

      There are two generic codes:
      P0125 Coolant Temp (Thermostat was recently replaced so this may be an old code.)
      P0171 System too lean Bank 1 (seems likely related to all the Toyota codes.)

      See this url and replace the Oxygen sensors apply in the view job diagram. Bank 1 is the bank with the odd cylinders 1, 3, 5
