    How much does it cost to replace the oil seal on the distributor coil side?
    I have about 130K miles on the engine. We replaced the valve cover seal and this decreased the amount of oil leaking; however there is still some leakage. My uncle believes the oil seal on the distributor needs to be replaced. Is there anyway of knowing this will ...

      When it broke the heater hose and you fixed and refilled it . Did you make sure all the air was bled out of the cooling system . What happens is there is air in the system and 99% of the time it is at the thermostat . With the air right there , the thermostat won't open . Also the fan switch is reading the same air pocket . It can't read air it HAS to read coolant . So it doesn't think the motor is hot and won't turn the fan on . So try bleeding all the air out and see what happens . If still the same . You might have got the motor to hot when the hose broke and have a chance there is now a cracked head .

    Slight fluctuation of RPMs when at cruising speeds
    2005 Honda Odyssey EXL with 105k miles. RPMs are fluctuating by 100-200RPMs at cruising speeds. For example, RPMs may be...say...2200 for a few seconds, then drop to 2000 for a few seconds, then repeats. This is a very suttle problem, and has only been going on ...

      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

      Thank you for your response Jimm. After changing out the air filter and adding a fuel injector cleaner to the gas, the problem has not improved. There is an error code: P0171 found. Does this mean anything to you?
    • Jimm
      8/19/2014 Jimm
      P0171 = System Too Lean (Bank 1)
      Basically this means that an oxygen sensor in bank 1 has detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1. The P0171 is one of the more common trouble codes.

      This code is triggered by the first downstream (front) O2 sensor. The sensor provides a reading of the air:fuel ratio leaving the engine's cylinders, and the vehicles powertrain/engine control module (PCM/ECM) uses that reading and adjusts to keep the engine running at that optimum ratio of 14.7:1. If something is not right and the PCM cannot maintain the 14.7:1 ratio, but rather there is too much air, it triggers this code.

      A code P0171 may mean that one or more of the following has happened:
      •The MAF (Mass Air Flow) Sensor is dirty or faulty
      Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
      •There could be a vacuum leak downstream of the MAF sensor
      •Possible cracked vacuum or PCV line/connection
      •Faulty or stuck open PCV valve
      •Failed or faulty oxygen sensor (bank 1, sensor 1)
      •Sticking/plugged or failed fuel injector
      •Low fuel pressure (possible plugged/dirty fuel filter!)
      •Exhaust leak between engine and first oxygen sensor

      Possible Solutions:
      A lot of times, cleaning the MAF sensor and finding/fixing vacuum leaks fix the problem. If you're on a tight budget, start there, but that may not be the fix for certain. So, possible solutions include:
      •Clean the MAF sensor. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
      •Inspect all vacuum and PCV hoses, replace/repair as required
      •Inspect all hoses and connections in the air intake system
      •Inspect and/or test the intake manifold gaskets for leakage
      •Check for a dirty fuel filter and proper fuel pressure
      •Ideally you'll want to monitor short and long term fuel trims using an advanced scan tool
      •If you have access, you may want to run a smoke test

      A code P0174 may mean that one or more of the following has happened:
      •The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters can cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors can leak the silicone potting material used to protect the circuitry.
      •There could be a vacuum leak downstream of the MAF sensor.

      Possible solutions include:
      •In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with MAF-specific spray cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
      •Inspect all vacuum and PCV hoses, replace if necessary
      •Check for a dirty fuel filter and proper fuel pressure

    Whenever I turn my car on the gas gauge goes down. It is like there is a leak but I can see no leaks. Also bad mpg
    I replaced my old exhaust manifold but I know that it was done correctly and it shouldn't be and issue

    Why does my car's gas gauge go down every time I start the car? It is like there is a leak but I see no leaks.
    I just replaced the old exhaust manifold but it seems to be running fine just my gas mileage is at about 20 when it is suppose to be around 30
