    1. Connect the intelligent tester to the DLC3.

    2. Start the engine and idle it.

    3. Push the intelligent tester main switch ON.

    4. Enter the following items: Powertrain / Engine and ECT / Data list / IGN Advance.

      Ignition timing:
      8 to 12° BTDC @ idle (Shift lever on N)
      HINT:
      Please refer to the intelligent tester operator's manual for further details.


97. CHECK ENGINE IDLE SPEED
  1. Warm up the engine.

    NOTICE:
    A warmed up engine should have an engine coolant temperature of over 80°C (176°F) and an engine oil temperature of 60°C (140°F), and the engine rpm should be stabilized.
  1. When using the intelligent tester:

    1. Connect the intelligent tester to the DLC3.

      NOTICE:
      Switch off all accessories and A/C before connecting the intelligent tester.
    2. Rev the engine at 2,500 rpm for approximately 90 seconds.

    3. Push the intelligent tester main switch ON.

    4. Enter the following items: Powertrain / Engine and ECT / Data list / Engine SPD.

      Idle speed:
      700 to 800 rpm
      NOTICE:
      When checking the idle speed, the transmission should be in neutral.
      HINT:
      Please refer to the intelligent tester operator's manual for further details.
      If the idle speed is not as specified, check the air intake system.


98. CHECK CO/HC


    Lexus Gs430, Gs300. Uzs190 Grs190.3Uz-Fe Engine Mechanical.Engine.Engine Assembly  Installation
  1. Start the engine.

  1. Rev the engine at 2,500 rpm for approximately 180 seconds.

  1. Insert a CO/HC meter testing probe at least 40 cm (1.3 ft.) into the tailpipe during idling.

  1. Check CO/HC concentration at idle and/or 2,500 rpm.

    HINT:
    1. Complete the measurement within 3 minutes.
    2. Check regulations in your area when performing 2 mode CO/HC concentration testing (engine check at both idle speed and at 2,500 rpm).
  1. If the CO/HC concentration does not comply with regulations, perform troubleshooting in the order given below.

    1. Check the heated oxygen sensor operation (Click here).

    2. See the table below for possible causes, and then inspect and repair.

      2. Fouled, shorted or improperly gapped plugs.
      2. Incorrect valve clearance
      3. Leaky intake and exhaust valves
      4. Leaky cylinder

      1. Vacuum leaks:
      1. PCV hose
      2. Intake manifold
      3. Throttle body
      2. Lean mixture causing misfire
      High
      High
      Rough idle
      (black smoke from exhaust)
      1. Restricted air filter
      2. Faulty SFI system:
      1. Faulty pressure regulator
      2. Defective ECT sensor
      3. Faulty ECM
      4. Faulty injector
      5. Faulty throttle position sensor
      6. MAF sensor


99. CHECK FOR ENGINE OIL LEAKS


100. CHECK FOR ENGINE COOLANT LEAKS
  1. Check for engine coolant leaks (Click here).



101. CHECK ENGINE OIL LEVEL
  1. Warm up the engine, stop the engine and wait 5 minutes. The oil level should be between the dipstick's low and full level mark.

    1. If low, check for leakage and add oil up to the full level mark.
      NOTICE:
      Do not fill the engine oil above the full level mark.
      HINT:
      SAE 5W-30 is the recommended choice for this engine for good fuel economy and good starting in cold weather.


102. CHECK AUTOMATIC TRANSMISSION FLUID LEVEL
