AbrahamsLincoln - 2001 Lincoln Town Car - Engine - 3/7/2015A week ago I smelled what seemed to be electrical wires burning. Couldn't pin point it. Couple days later my heating and cooling went. it just shut off in my dashboard. which led me to think it was a short. There has also been a rattling noise sounds like bad ...
mikemaine - 1999 Lincoln Town Car - Engine - 3/7/2015My car has individual coils and i have never changed coils like this.
lukyloser05 - 2002 Lincoln LS - Engine - 2/19/2015The 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 ...
CopperLincoln - 1992 Lincoln Continental - Engine - 2/12/2015We 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 ...
2/12/2015 Teddy BThe 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
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
Henry - 2004 Lincoln LS - Engine - 2/10/2015car hesitate when step on gas and have a noise not lode but can hear.
2/10/2015 JimmP0171 = 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
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 - 2/10/2015The code that came up is p0401
2/10/2015 JimmP0401 = 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
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
wayne - 1995 Lincoln Town Car - Engine - 2/5/2015We checked the fuses , we checked to see if it was getting gas? We checked to see if it was getting fire and its not?
Nanci - 2001 Lincoln LS - Engine - 1/27/2015Back fires and ex celebrates up and down
mariee vega - 2001 Lincoln LS - Engine - 1/19/2015it a clicking noise started lights and everything came on car just wont start
Connie - 2006 Lincoln LS - Engine - 12/13/2014Had 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 ...
12/13/2014 Teddy BThe 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
AutoMD Member - 1998 Lincoln Continental - Engine - 12/2/2014It act like bad gas but my gas is goodt
Silas - 2003 Lincoln Aviator - Engine - 11/25/2014Resevoir 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.
roy m. - 1992 Lincoln Continental - Engine - 11/20/2014pump stays on after engine shut off
margie androes - 2003 Lincoln LS - Engine - 11/19/2014Car will crank but it will not turn over and start. Don't have a scanner to check what is wrong,
