    Why does my car go up to 2000 rpms when idle?
    The cars rpms shoot up when the car is idle at a complete stop. It continues to rev on its own when stopped. The car does this everytime it is stopped.

      Either the engine is very low on coolant or the idle speed control is junk.

      I would say you have an open main fuse in the underhood fuse panel.Check and see if fuses 39 and 40 have battery voltage at the fuse. if there is no battery voltage there then the ELD is junk (electric load detector). If there is no battery voltage reading at the heavy wire at the alternator (there should be at all times) then the main fuse #41 which is a 60 amp fuse is open.

    How do I fix code p1077 on a 2002 Honda CR-V
    I took the car to AutoZone for them to read any OBDii codes because the check engine light came on. I got code p1077(IMRC assembly malfunction(valve stuck short)). So I looked this up on the internet and got two different ways to diagnose the problem. One told me ...

    97 Civic Ex tries to crank, but will not start. Where to start troubleshooting?
    This problem just arose today out of nowhere. I wasn't having any previous problems with the car. My fuel level was pretty low so when I went outside and it wouldn't start, my initial thought was I had ran it too low and didn't have enough fuel for it to fire. So I ...

      Stay with the basic flow of diagnostics first. Check for ignition spark. Yes / No ?

    Why does my engine have a rough idle until it reaches 2000 rpm
    Mileage 184,866. Engine feels like it's missing or has a dead cylinder on acceleration until it reaches 2000 rpm. Happens when hot & no engine light is 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

      I believe your noise may be related to this repair that was done with the water pump / belt / tensioner. The tranny fluid being overfull a quart wouldn't do anything and if it is more than a quart I have no data on that.

    Idles very rough, surges
    when I'm at a stop, if I shift into neutral, the idle smoothes out immediately

      Has plugs, wires cap and rotor been replaced yet? If not do so. Also replace the O2 sensor. Then update.

    I am pulling code p1077 which is a problem with the imrc assembly
    I have done several tests to the components of the intake manifold runner control assembly and came to the conclusion that the valve position sensor was bad so I replaced it and the idle is wild. how does the imrc assembly actually work? Does the valve position ...

      No the sensor just reports the position to the ECU. The actuator is turned by the vacuum actuator on the other end of the manifold.. I would replace the actuator if a P1077 is stored but better pay attention to installation detail. Lots of mechanics install it wrong and end up with the same code.

    My Pilot has 90,000 miles. A few days ago I got gas and did not tighten the cap all the way. My malfunction light came on and I tightened the cap after driving about 5 miles. The malfunction light went off a few hours later. The next day, the malfunction light ...

      There are two (2) O2 sensors; one each upstream and downstream of the catalytic converter. Each sensor has its own connector - there will be a wiring harness / pigtail group of at least two or three wires to each individual sensor on the exhaust system.
      It could be that the O2 sensor connector is simply missing / damaged - the wiring pigtail is available in the aftermarket as a separate item.
      The parts are readily available; try these on-line sources; www.partsgeek.com, www.rockauto.com, www.discountautoparts.com, www.autopartswarehouse.com, www.jcwhitney.com - to list only a few possibilities. In fact they (PartsGeek) list the O2 sensor pigtail and connector from around $8.00 for your vehicle.

      There are no rules here. You use whatever you have. Since I cannot know exactly what will not move because I cannot see it, I do know that whatever it is it is made of composite materials and tools can overcome composite materials that have melted / become stuck / whatever. If you mean that you removed the hold down retaining bots and the coil will not move up well then you pry it up with a screwdriver.

      It is right on the top of the right side of the engine on the top of intake manifold. Very easy job.
