      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

    Why does my car vibrate bad when I put it into reverse with the brakes applied?
    The vibration stops when driving in reverse. The same for drive but the vibration is minimal. I have had the motor mounts and torque converter replaced by a non dealer shop. I took it to the dealer for a diagnosis and they report a torque converter code error. The ...

    Kicks when driving or down shift

      This happens a lot when the basic settings for the transmission control module are not correct. A factory scan tool is required to reset basic settings.

    Why does my dash only read that my car is still in drive even when I shift it into Park to Neutral
    Car is parked and won't start because it thinks it's in drive. What might be the cause?

      Could it be the Neutral Start Switch? If so, where is it located?
    • CVO

      The combination neutral start and backup light switch is mounted inside the shifter housing. The starter should operate in Park or Neutral only. Adjust the switch by moving it on its mounts. The back-up lights should only come on when the shift selector is in the Reverse position.

      The neutral safety switch and back-up light are combined into one switch referred to as the multi-function Transmission Range (TR) Switch. The switch also supplies input for the on dash gear position indicators on models so equipped.

      The TR switch is also used to operate the back-up light.

    Why dose my car give a hard jerk when dropping speed
    After driving and hitting 5th gear when losing speed I get a hard jerk and not sure what it is coming from

      The check engine light doesn't have to be ON to store a fault code.

      Check the vehicle for fault codes to see if there are any sensors were involved to the malfunction of the engine.

      1.Local auto parts stores such as Autozone ( not in California) or Advance Auto parts or Pep Boys will scan and retrieve any diagnostic trouble codes ( dtc ) stored in the powertrain control module for free of charge..

      2. has the code reader for less than $ 18.00 dollars + shipping
      Autel MaxiScan MS300 CAN Diagnostic Scan Tool for OBDII Vehicles

      3.Re-post the dtc's in here " answer question " for further assistance.

      Note: we need the dtc's to identify the sensor, there are a dozen different ELECTRONIC sensors to operate the car.

      Visit this site and see all the different sensors.
      Powertrain Control Module (PCM)
      Throttle Position (TP) sensor
      Mass Air Flow (MAF) sensor
      Intake Air Temperature (IAT) sensor
      Idle Air Control (IAC) valve
      Engine Coolant Temperature (ECT)
      Heated Oxygen Sensor (HO2S)
      Camshaft Position (CMP) sensor
      Knock Sensor (KS)
      Vehicle Speed Sensor (VSS)
      Crankshaft Position (CKP) sensor

      It could be the vehicle speed sensor, but it's only a scan test could tell for sure.

    Were do you put transmission oil
    Low oil
      6/18/2014 JONES AUTO REPAIR
      transmission oil ( on an automatic ) will need to be put n the dipstick tube, ( on a manual ) should be a plug on the side of trans, this may be best performed by a transmission shop.

    Why would the gear selector light up all the gears while driving and not turn off until the car is turned off.
    The car continues to run fine and the gear selector resets and works fine after turning the car off for a while.

    Loud noise when gas pedal is not being pushed
    When I am driving if I am not pushing the gas (just costing) or letting up on the gas (to shift or slow down) there is a loud rattling noise and I can feel it vibrating in my gas pedal. Its loud enough that I know something is not working properly. Any thoughts on ...

      No clue - need more information. Where exactly is the noise originating from? From under the hood? From under the vehicle? Does the sound change with road conditions or vehicle speed?
      5/20/2014 AutoMD Member
      It sounds like it is coming from the front of the car. It sounds like a loud whining. It is very quite when going slow like in 1st... but gets louder the faster I am going. It only happens when I am letting off the gas. Other then that the car runs fine. It shifts great and does not give any other signs of problems.

    Where is the clutch reservoir located?
    transmission sticks in gear
    • GT500Knights
      5/8/2014 GT500Knights
      It should be located right next to the brake booster/brake fluid reservoir. Sometime there's plastic panels covering it and they need to be removed to expose the reservoir. If your transmission is stuck in gear, check shift linkage, shift forksand shifter assembly for anything that may be broken. If a cable has somehow detached from the shifter assembly, the transmission will not be able to shift out of gear.
