    Why does my car lack the power it used to have?
    It struggles when it goes uphill, the engine is louder and is generally slower to accelerate. Cat converter is new as of 7 months ago, O2 sensor is new as of 2 years ago. I think I got a fuel injection cleaning when I got the new cat converter too. Check engine is ...

      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

      Initially the family men got in the car to try and start it.you know there's just no way to tell them don't so they ran the battery down but the carb/ injection system would try to work the battery would try tosyart thr starter would try but only very little tick then nothing. Iam replacing the battery the alternator the starter and the O2sensor if no running then it gets to go to the engine rebuilders I'm fearful its a performance issue with the electronic devices how do I test those myself?

    Car shut down and wont start but cranks. Immobilizer or Main relay?
    190,000 miles and timing belt changed at 150000. Wont start at all but cranks. Could be fuel pump as well.

      This vehicle is equipped with an immobilizer system. When it has a problem, or it does not recognize the chip in the key, it will flash the green key light or turn it on steady. Do you see this key flashing or on steady?
      Next: Locate the Programmable Fuel Injection (PGM-FI) main relay, under the driver's side of the dash, by the brake pedal. The Black / Yellow wire powers the fuel pump. When the key is turned on, the engine control module will ground the Green / Yellow wire for 2 seconds so the fuel pump will operate. If there is no or low voltage on the BLK / YEL wire, then verify that the Red / White wire has good battery voltage. If the circuits are OK, then the common failure is the PGM-FI main relay.

    Can you clean a fuel pump? Would there be a need to ?
    I've been having a significant decrease in my overall gas mileage. So I'm wondering if the pump can or needs to be cleaned.

      No need. Its not the pump. Read fault codes first. try replacing the two upstream oxygen sensors.

      Try bleeding the cooling system! If that doesnt work get another thermostat! they come bad out of the factory!

      There is a bleeder screw on the thermostat housing. Get the air out.

    No interior heat but gauge gets hot
    540,000 kms Canadian climate. It happened once last year at -30 C. Recently, it was very cold again and the car ran ok but no heat and the gauge was going up to hot - it never gets that high, even in hot summers. One thing - I used the block heater on both ...

      When the coolant gets low, it gets that way because something is dripping / oozing / leaking coolant, slowly and not at all times but yes there is most likely a leak. when a Honda 1.5 engine gets low on coolant, the space inside the engine gets replaced with air which then stays there as an air pocket in the engine and that air pocket causes the thermostat to close down which blocks flow and causes an overheat. The pocket of air will not purge by itself, that is why Honda made a bleeder screw on the thermostat housing. So it seems likely that this is your cause here so at the very least rule it out by opening the bleeder and run the engine at idle until the bleeder just shows a steady stream of coolant coming out and then close it, but careful not to overtighten it. You might just see the heater come alive again and the gauge stabilize immediately after bleeding it and topping off coolant. Of course there could also be a bad water pump (not pumping from broken impeller) which would disable your heat and make you overheat as well. bad head gasket is possible too. Most times its air.

      I don't think it is air in the system but will check that as advised. I am pretty sure it shouldn't be a bad water pump because I have heat today (it is - 15 today). There seems to be a relationship with using my block heater (of course this is only used below - 25 C) and cold weather which somehow affects the thermostat. I only added about 0.5 liter of coolant today when I checked, so not much if any coolant was missing.

      Thanks

      And of course I should have also mentioned...a bad thermostat. The thermostat does not get diagnosed, you should just do it to rule it out.

    Why does is my car having trouble accelerating
    car had oil filter leak, lost all oil and died, i towed car replaced oil filter and oil, now when starting out car bogs and has trouble accelerating , moves slow then starts to speed up and has lacking power when shifted to next gear

      Ok. the oil leak if it was from just the oil filter should not cause a running problem.

      Check codes by jumping the two wires (Orange/Red and Green/White) in the 2-wire blue service check connector under the right side of the dash, near the right kick panel, and turn the key on and watch the check engine light on the dash flashing codes.

      my car does not have this 2 wire service check connector cant find it anywhere... check engine light is not on and to check codes on this model car there is a lcd light on the ecu under passanger feet.. and its not blinking any codes... the car will accelerate if i let the clutch out at at 3000 rpm but still bogs up a little when shifting and has a decrease and loss of power at higher speeds ... any other advice on what this could be..? thanks

      12/1/2013 HouseCallAuto
      yes the car could have come through eithert way. Either it has the LED light ion the ECU or it has the check connector but no both.

      So you are saying that immediately prior to losing oil from an oil leak determined to be at the oil filter, the car was running normal with no hint of the symptom you are new experiencing? Did the oil contaminate anything visually under the hood? Try unplugging the oxygen sensor connector and then see if power level improves.

      yes the car ran great before ... all this happened in a matter of 2 - 3 hours ...im confused ..... ill try unplugging the oxygen censor and see what happens.. thank tou

      Another possibility here is that the timing belt jumped a tooth or two. This would allow the engine to run but it would lack power severely. The belt alignment can be checked pretty easily.

      how do i check it...do i check it with a timing light ?
      HouseCallAuto
      12/1/2013 HouseCallAuto
      No, you need to remove the upper timing cover. Really hard to detail how to do this if you have no experience. Here is a picture of the timing alignment marks but that does not tell you how to do it. https://www.google.com/search

    Why does the idle fluctuate when car is in park
    the car has over 200,000 miles. the car was purchased recently and the idle sensor valve looks like its been recently changed. The idle fluctuates between 500 and 1500 rpm and sometimes the car surges forward at a stop. The check engine light is not on.

      So you either have to replace the idle speed control or you may be very low on coolant.

    I am towing my Honda accord with my motorhome. I am using magnetic tow lights and the run the battery down after 150
    miles. Someone told me to run a separate wire from the plus side of the battery to the hot wire coming into the hitch connector and it will keep it charged? will this work? Or what are some suggestions. Thank You Mike

      You should be powering the tow lights from the motor home.

      I am, but I need to have the ignition switch on or the steering wheel will lock up in the tow vehicle.
      This runs the battery down after a 150 miles. I have been told that I need to run a charge line from
      the motorhome to the car. What is the best way to do this? Sorry for the confusion on the first question, my other computer keeps dropping out words and letters.
      Thank You

      If there is no ignition spark there when it will not start, then your fix would be to replace the distributor.
