    Does this car have a MAF or an MAP or both?

      There is a MAP (manifold pressure) sensor on the 2.5L engine. It's main function is to sense barometric pressure at the air intake of the engine. Try the many on-line auto parts sources, such as; www.autopartswarehouse.com or www.rockauto.com for the replacement parts.

      First step - have the check engine light or stored fault codes scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply as 'add answer' for more assistance.

      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 a 99 Subaru Outback 2.2 L all wheel drive; the thermostat kept blowing out, so we left it out and
    just kept the fluids full. Then, it overheated. We replaced the thermostat again, and changed fluids, got it home and now it won't start. A friend said it was the fuel pump. My mother said it was probably a relay that overheated. How do I figure out what is wrong?

      Hello
      It sounds like you may have a head gasket issue. This should be diagnosed by your mechanic. It is a hard one to give a definite diagnoses without actually seeing what is going on.
      Hope this helps

      Hello
      If your A/C system was recently serviced it could have been over charged this could cause these symptoms.
      Or your A/C compressor could be starting to seize .
      Hope this helps

    Why is there smoke or steam coming from the back of the engine (close to the dash)?
    Whenever I go uphill for a prolonged period (1-2 miles), steam starts coming out from under the hood. It smells like burned rubber, and it seems to be coming from the center back area close to the dashboard.

      Most likely, the issue is a leaking heater core, or leaking heater hoses. Check on-line for the many parts supply sources, such as; www.autopartswarehouse.com or www.rockauto.com for the replacement parts.

      These are indications the cylinder head gasket is blown / leaking / faulty. Check on-line for the many parts supply sources, such as; www.autopartswarehouse.com or www.rockauto.com for the replacement parts.
