    What is causing 2003 Honda Accord to show a P0172 code (System too rich-Bank 1)?
    loss of power esp. when going up hills, using more fuel, hesitates to shift

      P0172 = System Too Rich (Bank 1)
      Basically this means that an oxygen sensor in bank 1 detected a rich condition (too little oxygen in the exhaust).
      A code P0172 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 leak the silicone potting material used to protect the circuitry.
      There could be a vacuum leak.
      There could be a fuel pressure or delivery problem

      Possible solutions include:

      Inspect all vacuum and PCV hoses, replace if necessary
      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, brake cleaner, or throttle body-specific cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
      Inspect fuel lines for cracks, leaks, or pinches
      Check the fuel pressure at the fuel rail
      Check the fuel injectors, they may be dirty. Use fuel injector cleaner or get them cleaned / replaced.
      Check for an exhaust leak before the first oxygen sensor (this is unlikely to cause the problem, but it is possible)

      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

    I have a 2001 Honda civic, that keeps overheating. The needle rises just above the half way point. This seems to happen
    New water pump and thermostat timing belt also. The resevior tank was over filled way to the top cleaned it out and filled it back up to the max line.

      The most common cause of overheating is because of an external leak from a water pump or a radiator or heater hose. The way to find the leak is to wait till it is overnight cold and maybe just pour water in and see if the leak is large enough to see it simply leak out from where it has a leak. if you pour in a half gallon or more and you still see no leak its time to pressure check the system.

      Here is a short list of possible causes for overheating;

      Low coolant level
      Leaking coolant
      Improper coolant concentration (not at recommended 50 / 50 mix of anti-freeze and water)
      Clogged radiator hoses
      Clogged heater hoses
      Clogged radiator passages
      Clogged heater core
      Faulty thermostat
      Faulty water pump
      Faulty radiator cooling fans
      Faulty radiator cooling fan switch (coolant temperature sensor)
      Faulty / worn serpentine drive belt
      Faulty / worn drive belt tensioner

      Thanks for the response. So I replaced the thermostat again took in inside the house a put it in a pot of boiling water. The thermostat never opened up it stayed closed...Hopefully this fixed the problem...the car seems to be running at normal temp the heater is hot again. It started to blow cold air this morning

    Ignition Coil Black Hold Down Nut
    I was changing out my spark plugs, and the Black Hold Down Nut which holds down the Ignition Coil broke off along with the thread. Where can I get new nuts and parts that are apart of the thread where the Ignition coil screws into.

      Possibly a local salvage yard in your area, or maybe a dealership item.

    The car will be running fine but then randomly it will lose power and turn off when ever mostly when I slow down. It tremors the shuts off. I don't want to mess up my starter by laying on it but more often then not it will turn back on until I reach my destination ...

    Temperture gauge going to red after long drives
    for the past month when i drive a long distance then stop at a stop light my temperture gauge will slowly go to the red mark. I checked my fans and they are working properly, replaced the thermostat but it still goes to the red mark.

      I'd use a temp reader and double check your gage reading. When it hits the red mark, I need the engine temp in degrees F. I do realize some temp gages don't give the actual degrees, they should, in my opinion.

      Some possibilities for over-heating, clogged radiator--radiator cap--coolant temp sensor/sender-- water pump-- combustion gases getting into the coolant caused by gasket issue, hopefully not something cracked. Clogged coolant passages.

      Are there any over-heating issues besides the temp gage?

      luckily i checked with a combustion tester at one point and the head gasket is good. there are no leaks but i will check with a temp reader.

      No combustion gases in the coolant, that is good.

    My son had a friend put a new radio in his car, they did it the old way by cutting wires and taping. shortly after
    things stopped working. the sunroof, the interior lights, the horn, the heater. now the car has to be jumped to start. it runs fine when started but if it sits more than ten minutes you cannot restart without jumping

      Remove the new radio, reverse and then repair the wiring damage to resolve the issues. Then, have a new stereo or radio professionally installed to avoid this problem in the future.

    Antifreeze was spraying out of my engine the other day, wondering what my best option is/what may be the cause?
    So I came home from the gym to smoke coming out of my engine, when I popped the hood there was a liquid spraying out from the engine. At the time I didn't get a good look at it, but upon looking closer today, there is a small pool of antifreeze in places on the ...

      Possible leak points include: hoses, the radiator, heater core, water pump, thermostat housing, head gasket, freeze plugs, coolant reservoir tank, automatic transmission oil cooler, cylinder head(s) and engine block.

      With the engine and cooling system cold - make a careful visual inspection of the entire cooling system, and then PRESSURE TEST the cooling system and radiator cap. A pressure test will reveal internal leaks such as seepage past the head gasket as well as cracks in the head or block. A good system should hold 12 to 15 psi for 15 minutes or more with no loss in pressure. If it leaks pressure, there is an internal coolant leak (most likely a bad head gasket but possibly also a cracked cylinder or engine block).

      It is important to pressure test the radiator cap, too, because a weak cap (or one with too low a pressure rating ).

      Perform a cooling system / radiator pressure test when the engine is " COLD" - as a first step to locate the leak.
      Obtain a loaner tool / free radiator pressure tester from the local auto parts stores such as Autozone, O'Reilly, NAPA, Advance Auto, or PepBoys. Follow their instructions and pump it to an adequate air pressure 12 -15 psi or up to the pressure rating listed on the radiator or reservoir cap. Observe the cooling system and components listed (above) for any leaks and perform the repair.
      Note: do not over pressurize beyond the pressure allowed by the radiator cap, then test the radiator cap as well.
