Lincoln had a problem with the cylinder coils. I am sure you have fixed yours already, but in the future if you run into the same problem, call your local dealer, they replaced 2 in my 2004 free of charge.

The coil is located over the top of the spark plug, the cylinder is the 3dr one back on the right side of the engine as u in front of the bumper.

How do u change the sparkplugs on a 2003 Linccoln Aviator. I cant even find them lol. Thanks Jen


The spark plugs are in the cylinder head under the ignition coils, which are under the cover on each rocker cover.

CAUTION! Spark plugs should be loosened 1/4 turn, then compressed air should be used to clear any debris from the spark plug tubes before removing the spark plugs. Failure to do this can result in debris falling into the spark plug holes and entering the combution chambers. This can result in serious damage to the engine.

Have 2005 lincoln aviator - has miss at 30-55 MPH - no codes replaced all coils ( ford) & spark plugs (twice) - repair vacuum leak at PCV Still misses -- no codes -- help


The COPS (coils) may have shorted the drivers in the PCM (computer). You should get a misfire code for each cylinder misfiring though.

Slim possibility, but very expensive unless you have a service contract.
LINCOLN: 1999-2004 Navigator
2002-2003 Blackwood
2003-2005 Aviator MERCURY: 2003-2004 Marauder
ISSUE: Some 1999-2004 Navigator, 2002-2003 Blackwood, 2003-2005 Aviator, 2003-2004 Marauder and 2003-2004 Mustang vehicles built before 12/19/2004 equipped with 4.6L 4V/5.4 4V engine may exhibit a runs rough, lacks power, and engine misfire, prompted by a MIL light and DTC codes P0301, P0302, P0303, P0304, P0305, P0306, P0307, P0308, and P0316.
ACTION: Diagnose engine for engine misfire concern. If diagnostics determine an engine misfire which is characterized by leakage through exhaust valve(s), only replace the affected cylinder head(s).
SERVICE PROCEDURE FOR VEHICLES WITH RUNS ROUGH/MISFIRE CONDITION:
  1. Perform relative compression check on all cylinders. If abnormal, check cylinder leakage and actual compression for "low" cylinders refer to Workshop Manual (WSM), Section 303-00.
  2. If leakage/compression check indicates a valve train concern, per valve train diagnostics in WSM, Section 303-00, replace cylinder head and cam assembly, pipe plugs and timing chain tensioner, per procedure outlined in WSM, Section 303-01.
  3. If cylinder leakage and compression tests are inconclusive, perform misfire diagnostic, per TSB 05-22-8. NOTE: DO NOT TRANSFER SPARK PLUGS. INSTALL NEW SPARK PLUGS IN REPLACEMENT CYLINDER HEAD AND CAM ASSEMBLY. NOTE: THE ENGINE MISFIRE CONCERN IS TYPICALLY EXHIBITED ON THE LEFT HAND CYLINDER HEAD AND RARELY ON THE RIGHT HAND CYLINDER HEAD. UNLESS CONFIRMED, THE RIGHT HAND CYLINDER HEAD SHOULD NOT BE REPLACED AS AN "EXTRA MEASURE" SERVICE PRECAUTION. NOTE: THE REPLACEMENT CYLINDER HEAD WILL NOT IMPROVE OR REDUCE ENGINE HORSEPOWER OR TORQUE ABOVE ADVERTISED LEVELS.

Have replaced engine coil and all sparkplugs and engine code/car still say missfire in same specific cylinder. what is possible remedy/solution?


Not spark plugs. Never was.
Bad coils.
Switch the COP Coil for the misfire cyl,and see if 300 code moves with coil.
Does it go into Failsafe or just get the MIL Light on dash?

I had the same problem. Maybe you still have some bad ignition coils. I would change them all out. Very simple to do yourself.

Also, check the hose that is connected to your PCV valve. Mine had a huge hole in it from melting and it was sucking in to much air.

THE PROBLEM SOUNDS LIKE THE COIL PACKS, THERE IS ONE FOR EVERY CYLINDER, LINCOLN WILL REPLACE THEM FREE I THINK UP TO 150,000 MILES. THEY WILL ONLY REPLACE FAULTY COIL(S).

Cylinder location diagram for a 2004 lincoln aviator


It could be a fuel injector problem on cylinder 5. Sounds like a failed injector. Run a compression check on that cylinder to make sure you have at least 100psi. Anything less than that would lead to either a burnt valve or a piston ring issue. Doing a compression check first will save you a lot of money.
