    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 ...

    Drastic Mileage Variance
    Mileage 5,000 Vehicle has gotten 28-44 mpg and after last tank of gas it has gotten 25-28 mpg. Driving habits remain unchanged. No indicator lights. Thank You Mike sumrecsvc@gmail.com

      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?
    I recently bought the car, with some surprises of course. I have noticed that when i have the Defroster/AC turned on, I will receive a vibration noise occasionally (not always). I have taken it to Honda as well and they were very vague about it, although they did ...

      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.

    Low idle and vibration
    I just purchased my 1985 Accord Hatch MT today and i've had the AC on since i've been driving. When I don't use the air conditioning the car idles very low around 300rpm and shakes the same way you are in too high a gear on the road. When I have the AC on the rpms ...

    Very low idle which causes shaking as if in too high a gear
    I just got the car and it has 100xxx miles on it. it idles extremely low but is fine if the ac is on cause this highers the idle rpm

      Sounds like your catalytic converter is plugged. I don't think your oil viscosity has anything to do with it. Your exhaust flow is reduced causing excessive back pressure. Have someone perform an exhaust back pressure test. This will cause it to run hotter. Remember a engine has to breathe in as good as it breathes out. That's why air filter and exhaust flow is very important. Hope this helps.

      One of several things may have occurred

      1. Blown head gasket
      2. Freeze plug blew out
      3. Water pump failure
      4. Radiator or heater hose may have worked itself loose or developed a leak

      Most likely, this seems like a head gasket going out. Improperly maintained cooling systems will eventually break down and cause something much larger and more expensive to give.

    removed valve cover to replace gasket and now engine wont fire from the distributor to the plug wires i have replaced the distributors parts and still have the same problem

      Never heard of that. I would check crank sensor signal. What kind of tapping noise did you have.
