      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.

      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

    My car runs smooth at idle but has a miss under a load
    I replaced the spark plugs. This vehicle has coil on spark plugs. All the coils have vertical hair-line cracks from top to bottom. They are the original coil Lucas part number 42533D. I check the oms and they all registered 100 but the specs that I have should all ...

      Replace the coil packs - this is most likely causing the misfiring. Check these various on-line vendors; www.autopartswarehouse.com, www.RockAuto.com, www.partsgeek.com, to list only a few. For example, they (RockAuto) list the coil from around $35.00 each for your vehicle.

    What is the correct way to check the resistance in a ignition coil?
    My jaguar sometimes idles rough and the engine is sluggish. On acceleration, it seems to have a definite misfire. I installed new sparkplugs and gapped them 35 thousandths. I used a higher octane gas and changed out the fuel filter. What kind of meter do I need to ...

      Sounds like you may have an injector or two that are not closing completely.
      Thus the stalling and the knocking sound when trying to start.

      Do a Parasitic Current Drain Test --to find out what circuit
      is not going to sleep & running your battery down

      You can find that on the internet & you tube video
