      Oil light came because of the oil pressure lose, and its due to engine failure to maintain idle RPM to keep the pressure up. Oil was not showing on your Dip stick because on the highway it was hot and thin now in the morning the oil temp. was cold and thick so when you filled it showed over the mark.
      If it died because of overheating , never fill the coolant while engine is hot it could lead to Thermal crack in Cylinder block. Your engine was shut down by overheating sensor which sensed the high temperature and shut down engine.

    Inconsistent acceleration
    It has about 131000mi. If you start the car it will stay on for a little bit then shut off. It almost sounds like it is choking. If you step on the gas, dark stuff sprays out of the tail pipe. I have had people tell me its the spark plugs or the catalytic convertor. ...

      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.

      This aspect is important; 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 oil light came on and I took it in. The mechanic said that I have a leak in the ac compressor, a leak in the oil pan gasket, and a couple of bad motor mounts. I replaced the ac compressor, the oil pan gasket, and 1 of the motor mounts. Since then, the oil ...

      You have already stated the possibilities; low oil level, faulty oi pressure sensor, faulty oil pump. Not motor mount or a/c compressor related.

    Hi....timing cover change = blown head gaskets?
    We finally took our beautiful copper colored 92 Lincoln in to have the timing cover gasket changed: it had been leaking coolant from there for 2 plus years. We pay the place 1,004 $ to do this job -they hint "after we changed the cover- the engine failed the engine ...

      The first shop could have done all sorts of tests IF you were willing to pay for that time

      Maybe they should have passed on a vehicle that old,now it bite them & you

      Yes you pay for all the towing always

      If your keeping it install a Reman Motor from
      Jasper Engine & trans or other vendor with
      a Warrantee

      Using it for 2 years when you knew you were loosing coolant
      may have caused the head gasket issue from over heating

      It is not a tragedy
      It is a 23 year old vehicle

      Folks have those issues with
      brand new fords & other products

      Hi Teddy B- Thank you for the opinions and info....Every opinion and bit of support is helping with this... Well---it's a tragedy if you'd see the beautiful "desert rose" color of the car and the leather interior.....Also- this car was the "dream car" of my girlfriend's mom and dad.... I've only worked on VW bugs....for 20 years....and 23 years old doesn't mean "throw away a car" to me.... We hesititated to fix the leak for those 2 or 3 years because of the cost of the repair.....sad...p

      P0171 = System Too Lean (Bank 1)
      Basically this means that an oxygen sensor in bank 1 has detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1. The P0171 is one of the more common trouble codes.

      This code is triggered by the first downstream (front) O2 sensor. The sensor provides a reading of the air:fuel ratio leaving the engine's cylinders, and the vehicles powertrain/engine control module (PCM/ECM) uses that reading and adjusts to keep the engine running at that optimum ratio of 14.7:1. If something is not right and the PCM cannot maintain the 14.7:1 ratio, but rather there is too much air, it triggers this code.

      A code P0171 may mean that one or more of the following has happened:
      •The MAF (Mass Air Flow) Sensor is dirty or faulty
      Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
      •There could be a vacuum leak downstream of the MAF sensor
      •Possible cracked vacuum or PCV line/connection
      •Faulty or stuck open PCV valve
      •Failed or faulty oxygen sensor (bank 1, sensor 1)
      •Sticking/plugged or failed fuel injector
      •Low fuel pressure (possible plugged/dirty fuel filter!)
      •Exhaust leak between engine and first oxygen sensor

      Possible Solutions:
      A lot of times, cleaning the MAF sensor and finding/fixing vacuum leaks fix the problem. If you're on a tight budget, start there, but that may not be the fix for certain. So, possible solutions include:
      •Clean the MAF sensor. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with MAF-specific spray cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling.
      •Inspect all vacuum and PCV hoses, replace/repair as required
      •Inspect all hoses and connections in the air intake system
      •Inspect and/or test the intake manifold gaskets for leakage
      •Check for a dirty fuel filter and proper fuel pressure
      •Ideally you'll want to monitor short and long term fuel trims using an advanced scan tool
      •If you have access, you may want to run a smoke test

      A code P0174 may mean that one or more of the following has happened:
      •The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters can cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors can leak the silicone potting material used to protect the circuitry.
      •There could be a vacuum leak downstream of the MAF sensor.

      Possible solutions include:
      •In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with MAF-specific spray cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling.
      •Inspect all vacuum and PCV hoses, replace if necessary
      •Check for a dirty fuel filter and proper fuel pressure

    sharhonda fate - 2000 Lincoln LS - Engine - 2/10/2015
    My car failed inspection, what does exhaust gas recirculation flow insufficient detected mean
    The code that came up is p0401
     
    • Jimm
      2/10/2015 Jimm
      P0401 = Insufficient EGR flow
      A code P0401 most likely means one or more of the following has happened:

      •The DPFE (differential pressure feedback EGR) sensor is faulty and needs to be replaced
      •There is a blockage in the EGR (tube), most likely carbon buildup
      •The EGR valve is faulty
      •The EGR valve may not be opening due to a lack of vacuum

      Possible Solutions:
      In fixing this code, it is quite common for people to just replace the EGR valve only to have the OBD code return. The EGR valve is not always the culprit. To determine the exact cause, follow these steps first;

      •Use a vacuum pump and pull the EGR valve open while monitoring engine RPM's & DPFE voltage. There should be a noticable difference in RPM's with the EGR open
      •Clean out the EGR valve and/or tubing to remove deposits
      •Check the voltage at the DPFE, compare to specified values (refer to a repair manual for your specific model)
      •Replace the DPFE sensor (with a good quality / OEM one)
      •Replace the EGR valve

      1. With the engine at operating temperature, take a hand-held vacuum pump and apply 1 pump of vacuum to the Exhaust Gas Recirculation (EGR) valve and the engine should stall instantly.

      2. If the engine does not stall, the EGR passages are likely restricted. To clean the passages, remove the plate on top of the intake manifold and clean the EGR passages. Once the passages are clean, the engine should stall instantly when the EGR valve is activated.

      3. It is not likely to be a bad EGR valve so do not buy one. the passages are clogged. 99% probability
