    New plugs, wires, and distributor. #3 cylinder has a miss.
    when you pull the plug wire off it doesnt change idle at as all other 3 plug wires do. when out of the engine the #3 plug is showing that it is getting fire. spark plug is jet black when i pull it out. ohm tested injector and its good. could it still not be getting fuel

      this could be a couple of things, air leak at the intake of that cylinder, compression, or that cylinders injector
      to determine if you have a intake air leak carefully spry a little quick start at the intake where it goes into that cyl when it runs and if the rpm goes up that's what it is. to determine if it is the injector is a little harder, you have to change the injector from that cyl with another one and if the miss changes to the to the other cyl then it's the injector.

    Why can i only start my car with jumper cables?
    i have about 290000 miles on the minivan and i just replaced the alternator, but my car still won't start unless i give it a jump. could it be that i just haven't charged the battery enough after i replaced the alternator or do you think its something else?

      check to see if the battery has enough reserve power, do a load test on it, check all connections from battery to starter, last but not least do a starter draw tst

      check for power to the horn switch then check for power coming out of switch usually the problem is in the switch. the other quick check would be check for power and ground at the horn.

    Check Engine Light - Toyota dealer said the oxygen sensor was bad.
    Dealer replaced the oxygen sensor then told me the light was still on and they think it is a computer problem or short. Is it possible it wasn't the Oxygen sensor originally?My question is whether or not i should have to pay for them to fix it. Could this be their ...

      The check engine light is located on the dash and stays on if the computerized engine control system detects an engine performance or emissions problem.

      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.

      if the light is still on then the code is still there, they should have provided you with a print out of that code. some times its the a/f ratio sensor and not the oxy sensor which is up stream.but if they told you what it was and replaced a part that didn't fix it they should either follow up on it or refund ur money.do you know what code the scanner pulled up?

    Why does engine misfire below 1500 RPM ?
    Oxygen sensor was replaced but check engine light code is five flashes then pause then six flashes. The engine has 318,000 miles. With summer fuel blend, engine began to ping on driving up hill. Then began to shake when accelerator is released.

      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

    Cause of engine knocking when engine is cold
    once engine is warmed knocking stops

      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.
