    The car won't accelerate, making a REMARKABLE noise, smokes like a demon!
    We were told that the "high-idle" was being caused by bad plugs and plug-wires. We changed the wires first, started the car, and all heck broke loose! Thick grey smoke from the exhaust, the WHOLE CAR was rocking and lurching in, what felt like, every direction. It ...

    What could cause my car to crank but not continue to run?
    I have a 2005 Hyundai Accent 4 Cylinder. My timing belt broke while I was on the interstate. I have replaced the timing belt and the spark plugs. The car will start and run for a few minutes then shut off. I've been told the valves may be bent, I'm hoping its not ...

      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

    My car will not start. Ok about a month ago it started taking a lot more cranking to get it to start.
    It would take so long to start you would almost give up. Then it would start run a little sluggish then smooth out. I changed the crank shaft sensor after it wouldn't start again. No difference. I have a fully charged battery and half tank of gas. Already checked my ...

    Is it hard to repair a P0112 Intake air temp issue? How much?
    Just found today. Trying to figure what I can do or is this something deeper.

      P0112 = Low voltage for the IAT 'intake air temperature' sensor

      Try disconnecting the electrical connector from the MAF and drive the car (road test) and see if the hesitation is gone. When the MAF has an open circuit, the computer sees that and substitutes a fixed value in place of the open circuit which would supply nothing. The car will most often run better on the fixed value when the MAF sensor is really defective. But with a code P0112 you are pretty safe changing the MAF sensor.

      It could just be a bad connection at the connector or cleaning the MAF sensor with MAF aerosol cleaner might actually fix it. The spray can cleaner may cost around $5.00 - local auto parts stores.

      Check the various on-line vendors; www.autopartswarehouse.com, www.RockAuto.com, www.partsgeek.com, to list only a few. For example, they (RockAuto) list the MAF sensor (new) from around $82.00 for your vehicle.
