    There is a mysterious rattle when I accelerate
    This rattle sometimes happens when I just start the car as well. But mainly when I am accelerating and the rattle happens at 1500-1600 rpm. This even happens sometimes when I am maintaining speed and that is at that rpm. My dad and I thought it was a heat shield but ...

      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.

      This aspect is important; there may be a fault code stored in the OBD memory which may not be displayed as a check engine light.

      Do not skip this important first step - there are literally hundreds of possible fault codes. Avoid wasting/ throwing money at the problem.

      As the first step - check the engine oil level and fill as necessary.

    My truck starts fine but once I put it from park to drive, it will stall and engine will turn off.

      Sounds like your starter has a parasitic load/drain, you need to make sure the ignition wire isn't pulling any voltage, it should be at 0.00 volts with key off

      Are there any other problems like lights that stay on, noises, and just to make sure the battery isn't bad do a home load test. With a voltmeter hookup the leads to the battery terminals and make sure you have 12.6 volts. Then turn the key on and create a load by turning on the ac system bright lights and parking lights, if the voltage drop to 9.5 volts or lower then your battery is bad

      I did all that what I just done was I took the ground cable off the battery and hooked the test light to the battery and ground cable and it was on very bright indicating i had something pulling fire. I pulled the fuse one at a time until it went out.
      I found the cooling fan is pulling. I replaced the cooling fan switch a couple of months ago.I guess it done went out again but the fans come on like they supposed to the does not run hot.

    What would cause my 01 mercury van to miss and jerk going down the road?
    The vans tach also moves so there is some sort of miss. I think it may be the O2 sensor but not for sure. It seems to do it worst after it is warmed up and is not as bad when it cold. It seems to be worst in overdrive also. The check engine light does not come on ...

      This aspect is important; there may be a fault code stored in the OBD memory which may not be displayed as a check engine light.

      Do not skip this important first step - there are literally hundreds of possible fault codes. Avoid wasting/ throwing money at the problem.

      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

    Why won't my car start up when I turn on the ignition? Why won't the horn blow or the lights come on?
    The first signs of something going wrong was when, while driving, I would turn on the heater and a few minutes later the battery light would come on. I got it to a mechanic and he tightened a bolt on the battery (or related piece) and the car started up just fine. ...

      Make sure the battery has a full charge. Check the battery cables positive and negative. Do you have a friend or somebody that can check that out for you?

    Engine turns & makes an attempt to start sometimes but does not start.. What else needs to be checked?
    Car used to start but only if you kept on the starter for about 30 sec. Now It does not start at all. Once in a while it makes a try for a second but does not start. What should I check & what may be the problem? No warning lights on. Vehicle was run hot a few times.
