      No such Ford vehicle as the 2000 model year Tempo. At any rate, first step is to check the fuses, wiring harness and connections at the motor itself.

      If the car engine cranks normally but won't start, at least you know that the battery and the starting system are working. If the battery was low on charge, the engine would crank very slow or wouldn't crank at all; if the starter was bad, the engine wouldn't crank. So let's look at what else is needed for an engine to start and what are the common problems:
      -Compression in the engine cylinders
      -Proper timing
      -spark
      If still there is problem i suggest you to visit an auto electrician

      is it the engine weak or the trans slipping if it is the engine and only doing it under a load i would look at fuel filters or air filters mabey a tune up if it has a lot of miles on it. if it is the trans acting up i would start by checking fluid level and look at the oil sould be clean red if it is black or brown there is bigger problems letting clutches slip burning the oil. are there any codes pressent?

      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

      This code means that your exhaust catalytic converter is failing. Replace it.

      I replaced the catalytic converter about 2 years ago .
    • Jimm

      P0420 = Catalyst system efficiency below threshold (bank 1)

      A code P0420 may mean that one or more of the following has happened:

      Leaded fuel was used where unleaded was called for
      A damaged or failed oxygen sensor (HO2S)
      Downstream oxygen sensor (HO2S) wiring damaged or connected improperly
      The engine coolant temperature sensor is not working properly
      Damaged or leaking exhaust manifold / catalytic converter / muffler / exhaust pipe
      Retarded spark timing
      The oxygen sensors in front and behind the converter are reporting too similar of readings
      Leaking fuel injector or high fuel pressure
      Cylinder misfire
      Oil contamination

      Jimm is right can be caused by oxygen sensor failure

      The vehicle heater core might broken, and the coolant leaks caused that burning oily smell.

      You haven't givent enough detail on your problem. Rough idle can be due to many problems. To name a few: fouled spark plugs, dirty fuel injectors, problem with iac valve, vacuum leaks, etc. need more detail to be able to help you.

      It could be the fuel pump relay, it's very common on Honda.
