      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.

      Do not skip this important first step - there are literally hundreds of possible fault codes. Avoid wasting/ throwing money at the problem.

      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

      The check engine light is located on the dash and stays on if the computerized engine control system detects an engine performance or emissions problem.

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.

    Engine turns over AOK but wont start after being run and engine hot. Turn over aok but wont run Sit a while and starts.
    turning off key several times and back on with several minutes off the engine will start and run perfectly with no trouble or indication of a problem. Just unreliable starting up. Fuel pump had been changed several years ago.

      Thanks for the reply.

      I can't really get the car to a store to have them check the code since it won't start. I'll probably just end up having it towed to my mechanic and hoping for the best.

      Borrow or rent (for a small fee) a fault code reader from a local auto parts store - or borrow one from a friend. May just save the cost of the towing charge.

      The ODB-II / ODBII system is universal on all models after 1996 -simply plug in an OBD 2 code reader.
      Check this link for all of the Honda OBD codes; www.engine-codes.com/year/1998/HONDA/civic


      For the OBD 1 diagnostic system (before 1996 model year); first, determine and record the code by watching the the CEL flash.
      You will get a series of long and then short flashes. A long flash is valued at 10 points and a short flash is valued at 1 point. You may have more than one code and this is displayed by a long pause after the short flashes. If a second code is present, the long flashes will begin again after the long pause. Add up the 'point' value of each code to get a number of 1-92. You may want to watch the cycle of code(s) a couple of times to ensure you can record all of the codes.

      P1009 HONDA - Valve Timing Control Advance Malfunction
      Possible Causes

      - Engine oil level
      - Dirty engine oil
      - Check VTC Strainer for blockage
      - Faulty VTC Oil Control Solenoid or circuit
      - Faulty VTC Actuator
      - Engine mechanical problems

      A stretched timing chain or damaged tensioner can also cause / trigger the P1009 code. Before replacing timing chain or tensioner, check engine oil level and condition. Replace the engine oil and filter with factory recommend oil weight if necessary.

      Several possibilities; worn / faulty wheel bearing, worn/ faulty suspension bushing, worn / faulty front strut or strut mount, tire / wheel out-of-round, wheel out of balance.
      Check the 'How-To-Guides' feature on the AutoMD website for the specific steps to inspect / diagnose suspension and steering issues.

    Fuel gauge is 2 bars off when full. it will never show full
    changed fuel pump and sending unit. did not fix the issue.

      Test your fuel level sending unit to find the resistance specifications and test the signal wire with the unit out of the tank, flex the arm and check to see that it is in spec.
      If this tests OK then check the fuel gauge/ instrument cluster.
