      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

    When does my car temperature go up?
    Temperature gauge of my car rises above middle line and keeps going up while the a/c is on but drops below middle line once the a/c is off and remains below the middle line.I have stopped the use of a/c for this reason.What can be the cause?

      Loss of coolant because of a coolant leak is probably the most common cause of engine overheating. Possible leak points include hoses, the radiator, heater core, water pump, thermostat housing, head gasket, freeze plugs, automatic transmission oil cooler, cylinder head(s) and block.

      Make a careful visual inspection of the entire cooling system, and then PRESSURE TEST the cooling system and radiator cap. A pressure test will reveal internal leaks such as seepage past the head gasket as well as cracks in the head or block. A good system should hold 12 to 15 psi for 15 minutes or more with no loss in pressure. If it leaks pressure, there is an internal coolant leak (most likely a bad head gasket but possibly also a cracked cylinder or engine block).

      It is important to pressure test the radiator cap, too, because a weak cap (or one with too low a pressure rating.

      1. Perform a cooling system / radiator pressure test when the engine is cold - as a first step to locate the leak.
      Obtain a loaner tool / free radiator pressure tester from the local auto parts stores such as Autozone, O'Reilly, NAPA, Advance Auto, or PepBoys. Follow their instructions and pump it to an adequate air pressure 12 -15 psi or the pressure rating listed on the radiator or reservoir cap. Observe the leaks and perform the repair.
      Note: do not over pressurize beyond the pressure allowed by the radiator cap, then test the radiator cap as well.

      2. Air pockets trapped in the cooling system can cause the engine to overheat. Some cooling systems have air bleed valves built into the system to aid in the removal of air pockets. Advice: For many cooling systems, the method of removing air pockets is to start the engine and allow it to run with the radiator cap off or loose until all the air escapes from the neck of the radiator. For some systems this method is not sufficient, and the manufacturer has installed air bleed valves usually near or on the thermostat housing.

    Is it ok for the shop who is at fault to replace my engine with a used one and not a re-built?
    my car had an oil change by the following day while driving to work my car suddenly broke down while i was on the freeway, got towed and i was told that there was no oil filter. engine is down. the shop agreed to fix it but will not use a rebuilt engine, but will ...

      A used engine maybe OK - depends on the condition; mileage and warranty. Does the shop warranty the engine and labor for some period in writing?

    Have a 335 code for crank pos. sensor. replaced sensor still have same code and problem.

      P0335 = Crankshaft Position Sensor "A" Circuit Malfunction
      CIRCUIT DESCRIPTION
      The crankshaft position sensor, which detects the engine speed and crankshaft angle signal (NE signal),
      has been installed on the oil pump body.
      The NE signal plate has 34 teeth. The NE signal sensor generates 34 signals at every engine revolution.
      The ECM detects the standard crankshaft angle based on the G signal, and the actual crankshaft angle and
      the engine speed by the NE signal.

      No signal of crankshaft position sensor to ECM during cranking
      (2 trip detection logic)
      No signal of crankshaft position sensor to ECM with engine
      speed 600 rpm or more (2 trip detection logic)

      Possible issues;
      Open or short in crankshaft position sensor circuit
      Crankshaft position sensor
      Crankshaft timing pulley

      P0318 - Rough Road Sensor Circuit;

      P0138 = Oxygen Sensor Circuit High Voltage (Bank1, Sensor2)

      The Heated Oxygen Sensor (2) located rear of catalytic converter produces an output signal relative to oxygen storage capacity of catalytic converter. Ho2S 2 signal is less active than signal produced by front oxygen sensor. This code sets when HO2 Sensor voltage is greater than 999 mV for more than 2 minutes (time depends on model. Could be as high as 4 minutes)

      A code P0138 may mean that one or more of the following has happened:
      Faulty O2 sensor
      Short to battery voltage in O2 sensor signal circuit
      High fuel pressure (not as likely)

      Here are some potential solutions:
      Replace O2 sensor
      Repair short to battery voltage in O2 sensor signal circuit

      Check these various on-line vendors; www.autopartswarehouse.com, www.RockAuto.com, www.partsgeek.com, to list only a few. The upstream O2 sensor is around $100,00,and the downstream sensor is around $29.00 for your vehicle.

      Always replace the O2 sensors in sets or pairs - due to mileage / age / wear considerations.

    Why does my car stall when I start it?
    When I try to start my car, it just stalls out unless I hit the gas right away and rev the engine. Also, it can be idling and then I turn on the heat and it stalls.

    My car is leaking oil really bad...could it be my oil sending unit?
    I just changed oil filter and I have to keep adding oil every day.

      I would look at the oil pan bolts. They can and do loosen over the years depending on the driving conditions. Oil filter may not be installed completely and needs another turn to tighten. Oil pan drain bolt gasket may be chipped or broken or just smashed flat. Front or rear crank oil seal could be the prob. Could be your timing cover leaking. i hope i did shed some light for you. It is kinda hard to assess with out a Visual.

    High idle and car surges sometimes
    idle fluctuates when driving car surges when just driving down the street. sometimes it does it when at a stop but mainly whn im driving

      it sounds like a vacuum leak.
