    Why does my OIL LIGHT KEEP COMING ON?
    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

    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

    Throttle Body Assembly
    Had car towed in as shaking,squealing noise. Put new serpentine belt and tensioner and new battery. The place said need throttle body assembly about another $1000. Already paid 695.00 Another shop tells me the throttle body assembly is a recall part. One shop ...

      The Throttle Body is not $1,000

      It is not on recall

      3W4Z 9E926 AD $334.19 (370.95 with shipping) from Tasca Ford

      There is NO Failsafe that requires a throttle body on a Lincoln L/S
      all those TACM codes come from bad COP Ignition coils

      Save your money on Seafoam-- we are not back in the 1850's next to
      some Gypsies pedaling a bottle of Doctor Do Good--waste of money (not a fix for anything)

      I know this question is old
      I also know many shops & dealers do not fix Lincoln L/S problems

      I own one & have 11 years diagnostics with that car

    What will cause no warm air through heater coolant res to fill and overflow and temp gauge to spike
    Resevoir will fill and overflow shortly after starting will get no warm air through heater and after driving for a bit temp gauge will spike but car doesn't seem hot and when you let sit while off for a couple minutes will go back to normal. Had thermostat replaced.

    Why is my car stalling on startup, and idle even when warmed up during winter?
    Once it is cold enough to snow, When I go to start my car it will stall out unless I am giving it some gas. Even when my car has warmed up, it will stall out if I try to let it idle. This only happens when it is cold outside, anything near 40 degrees and up and ...

    Why is my car stalling while idle during winter.
    If I am not pressing the gas slightly when I start the car up, it will stall out right away. Even after the car has warmed up, it will stall if I try to let it idle without pressing the gas a bit. It only does this when it is cold enough to snow out. Otherwise it ...
