      The #1 cause of loss of spark on Honda 1.5 engine is a bad distributor ass'y. it could be a bad igniter, a bad ignition coil, a bad TDC sensor or a bad pickup coil. All these components are located within the distributor. The cost of just the coil and / or the igniter will be near the cost of a REMANufactured distributor ass'y which will come out of the box with all of these components already inside the distributor.

      Pull the code from the vehicle. Report it here. You can go to any auto parts store and they can pull codes for free. It will help wih diagnosis of your hesitation issue.

      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 used JB Weld on a high pressure side aluminum pipe that had a groove worn through the pipe from years of vibration of nylon vacuum tubing rubbing on the top of one pipe. It worked like a charm. Apply and do not recharge the system for 48 hours so it fully cures. Hint: Only apply the epoxy after it has been completely mixed and it has begun to stiffen slightly, like toothpaste, that way it will not ooze into the inside of the hole in the pipe. Make sure you use a solvent (brake parts cleaner good) to remove all traces of grease.

    I replaced my car windshield about 2 years ago. Not sure if that is the cause of the leakage or if it's the air intake (
    Soon after that, I started to noticed dampness on the driver's floor. I blew it off thinking that I accidentally left window cracked. Happened a few more times, started to notice more dampness. The privately-owned glass biz who did my windshield suggested it could ...

      Poor fuel economy can be due to a great number of things. Even if the check engine light is not flashing or illuminated, there still may be a stored fault code. Have the OBD system scanned for free - at any local auto part store - then post a reply with the results for further assistance.

    Mileage change from 38-44MPG to 24-28 MPG's Mileage on vehicle is 5000, driving habits haven't changed. Something seems
    Mileage 5,000 No Indicator Lights other than tire pressure.

    Failed emissions for CO monoxide, and Hydrocarbons have replaced distributor and power pack module, plugs, cap rotor
    212k runs good no smoke no error light, failure is way high, I have till Monday for re test. Tomorrow I will test TDC and would like to know what part you would recommend to replace, if you had only one day to work on car

      Would you be able to post a picture of the smog test? That, or type out the numbers for each gas measured, along with max, avg, for each speed (15 and 25 mph). Make sure all gasses are included (HC, CO, o2 , co2, and NOx). Include other details such as rpm, timing, etc .... It shows that stuff above the smog results.

      Thanks
      NOx .1 @ 15 mph 33 @ 25 mph reading .0815 limit 3.0000, HC 5.0 @ 15 mph same @ 25 reading 2.8149 limit 1.2000, CO2 540 @ 15 mph same at 25 mph reading 203.1001 no limit,
      CO 60.0 as a plateau mostly throughout entire cycle all other readings had sharp peaks and valleys Reading 160.5956 limit 15.0000, Thanks again going to check TDC now

      Alright....based on what you gave me you're looking at a very large amount of incomplete combustion. Refer to the images.

      1. Bad ECT (Engine Coolant Temperature) sensor. The ECU measures resistance across the ECT to determine engine temperature and thereby control fuel injection pulse width. If ECT returns incorrect signal, injection pulse width can be too long, enriching the fuel mixture too much.

      2. Leaky fuel injectors.

      3. Thermostat stuck in open position/coolant leaking past thermostat. This one will allow your engine to run too cold. Colder engines use a richer fuel mixture. If the ECT is working properly and the thermostat is stuck open or is leaking, more coolant than is metered will be allowed to reach the radiator.....causing excess cooling.

      4. Excessive air filter restriction. Replace air filter.

      5. Catalytic converter. Its purpose is to burn up any unburned hc from the engine and to reduce nox. a properly operating cat will be at least 100 deg F hotter on the tail side of it compared against the opening side of it. This is measuring after a good 10 minute drive. That, or run the engine at about 2500 rpm for a couple minutes.

      Good luck.

      Checked TDC and re checked timing even at adjusting all the way over I'm at 25 deg. BTDC, checked error codes and got VSS code and fuel pressure regulator code. So my plan as well as check as much of your suggestions as I can is to pull timing belt from top sprocket turn the distributor back 1/2 way re install timing belt, get timing to 15 BTDC check VSS and replace fuell pressure regulator and possible O2 sensor if that don't work a mechanic will charge what the cars worth and its trade time

    The car began sputtering like it was running out of gas.. I could hear the fuel pump and another sound like air suckin
    My fuel pump is located in the gas tank

      First make sure you have enough fuel. I know it sounds stupid to state this but it's the simplest things that can go wrong.

      The air sucking sound is probably a large vacuum leak or a hose that isn't connected. Ensure all vacuum hoses are connected and that none of them are brittle. A test to check for vacuum leaks is to spray soapy water around the area that you think may be leaking. If the engine smooths out , you found your problem.

      If the fuel filter is clogged , not enough pressure will reach injectors.

      If fuel injectors are dirty, same issue.

      Timing belt may have jumped time or stretched too much.

      Excessive Exhaust back pressure will cause rough idle. Idle back pressure should not exceed 1.25 psi and back pressure should not exceed 3 psi at rpm speeds of 2000-2500 rpm

      Thanks for your help. It looks like I’m not getting any spark to the plugs. Someone loaned me a ohm meter and the reading I got was a 1. Any ideas of what the problem might be?

    How can I diagnose weather my AC Clutch is bad rather than the AC Compressor?

      Most compressors come with a clutch.The gap is critical on plate style clutches. More than likely the vibration is caused within the compressor like a bearing.
