      The english here is confusing me. Could you get help with translation and I will try to assist you? "panel beaters"? Check engine light? Can you plug ion a code reader and read fault codes? Can you detail the white smoke further? How does the engine run?

    In replacing "Flex pipe" what piece causes the loudness?
    car is very loud, runs great.

      The catalytic converter incorporates a "flex pipe" into it. So not sure what you are asking for exactly. You would purchase a complete new catalytic converter ass'y. If you go online and look it up you will see a flex pipe in it. The flex often cracks and makes noise. But you have to confirm what it is that you need.

      It gets ear piercing noise from the flex pipe breaking off at connection to the exhaust pipe

      Replace both upstream O2 sensors and if that does not solve it then you have a clogged catalytic converter on that bank.

    Blowing Fuses on am 2 circuit
    Why is it blowing fuses on the AM 2 circuit, but won't blow it with mass air flow sensor disconnected
     
    • alex

      Ohm check your mass air flow sensor. You shouldn't have low ohms anywhere in the plug. I would say its shorted inside but I would check it first. Those are kind of spendy

    Battery and starter checked out good, fuses all good. car wont turn over clicks only when ignition at starting position.
    what else would cause the car not to start
     
    • HouseCallAuto
      3/22/2014 HouseCallAuto
      Describe the click or clicking. A single heavy click or clicking that keeps clicking for as long as you hold the key in the start position? Turn on the headlamps and stand in front of the cxar so you can clearly see the headlights on. Have someone else turn the key to start the engine and look at what happens to the headlights. Do they go dim or shut off or there is not much change at all?
    • AutoMD Member

      there is a single click when starting the car. head lights go dim, click and swishing sounds from starter
    • HouseCallAuto

      So if the headlights dim out then that indicates a battery issue. Try the same test again only this time have jumper cables attached and see if it starts up.

      There are abs codes and the scanner you are using can only read engine codes (P-Codes) so buy a code reader that is abs capable. When there is an abs code of any kind the computer will disable the traction control system and the abs and will illuminate both lights. As for the speedo and tach, that sounds like a bad cluster.

    Random symptoms, don't know if related. 183k+ miles, had car for last 7k, these started one by one a couple months ago
    -Engine RPM's fluctuate when idling after starting, before shifting into drive (approx. 100 RPM-range in either direction; stabilizes once shifted into drive) -1st gear acceleration more sluggish than it used to be (takes a long time to get up to speed from a full ...

      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

      The fuel smell may be related to fuel system leaks; fuel line, fuel filter, clogged charcoal canister (evaporative system), fuel injector seals.

    99 4runner coolant leak
    coolant leak on the drivers side, front end of the motor. Top and bottom radiator hoses are dry. does not leak all the time. Removed skid plate to look for leak. Can't see anything. Assume it's the water pump but it is covered up by other motor parts.

      Probably is the water pump.

      is there any way to test the water pump while it's on the truck?
    • Jimm
      3/17/2014 Jimm
      Have an inexpensive (or free - with loaner tool from local parts stores) cooling system pressure test performed to determine the coolant leak source.

      If the water pump is the culprit - use these resources for the repair steps involved; www.autoMD.com 'How-To-Guides' and the website; www.autozone.com.

      The parts are readily available from these many on-line sources, www.partsgeek.com, www.rockauto.com, www.discountautoparts.com, www.autopartswarehouse.com, www.jcwhitney.com - to list only a few possibilities.
      In fact, they (RockAuto) list the water pump from around $25.00 (with gasket) for your vehicle.

      will the pressure test tell me it's the water pump or only tell me if the radiator is leaking
    • Jimm
      3/18/2014 Jimm
      Yes, the cooling system pressure test - with the engine cold - will show the specific leak point, wherever the system is leaking.
