      Did you check for a failed battery or charging system?

      I would hope you have a local shop you go to several
      times a year for many years,need that before you have a problem

      No one knows what is wrong

      You have to test vehicles to find problems
      you can't guess at it

    Car has a rough idle and smooths out under acceleration and running speeds.
    A mechanics code reader discovered an injector problem in the rear bank of cylinders. An Auto Zone code reader discovered a bad knock sensor but did not find an injector issue. What is involved in making either of these repairs and how can we narrow down what ...

      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.

      Your vehicle has an inertia fuel shut off ( IFS ) switch.A safety device that cuts power to electric fuel pump if a collision occurs. Switch must be reset manually.
