Dale - 2001 Toyota RAV4 - Engine - 9/12/2014Is there any difference in the rest of the equipment?
9/12/2014 JimmPurchase 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.

9/12/2014 JimmFirst 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

AutoMD Member - 2000 Toyota Camry - Engine - 8/15/2014New 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.
8/5/2014 CVOThe 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
8/15/2014 AutoMD MemberSorry 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.)
