      Typically a question of supply and demand - if there is sufficient demand, you may sell the parts available. If no demand, then you have a collection of parts.

      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

      one is sensor voltage code the other tells you its the right side o2 sensor. the low voltage sounds like either unplugged or broaken wire.

    My Audi takes about two tries to completly start how can I fix this?
    About 8/10 my Audi takes atleast two tries to fully start. The CE light is on and the two codes that read are P1121 and P1140. I believe that both have to do with HO2 sensors and I have already had one replaced. Any suggestions to what I can do next to fix this ...

    Hello, I was test driving a 2014 Audi Q5 2.0T at a dealership and noticed that the 'Check Engine' and EPC Light came one during the test drive, which I brought to the attention of the salesperson. The salesperson obviously couldn't let me purchase the vehicle and ...

      Need to know the specific fault code light (check engine light). There may be a specific issue that the dealership has corrected / repaired with this vehicle.

      Nevertheless - it is a warning, and if it were me - I'd buy a different vehicle altogether - avoiding the one with the check engine light issues.

      Josh, there is no substitute for putting the car up on plastic Rhino Ramps and looking to see where the coolant is coming from. Maybe after you have a better idea of the general area of the coolant flow we can help you further.
