Look along the Engine head for round plastic pieces with 2 wires going to each. There will be 6 or 8 of these depending on if you have the V6 or V8 engine. You may not be able to see a few of these because of the way the motor is installed. I know on my Escape I have to remove the Air intake to replace the back 3 on my V6. It's a way to force people to go to the dealer to do what would normally be an easy job.

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 a 03 aviator when i get gas the car does not run right. It will not go into gear and the rpms go high before it will shift... have had vacum hose replaced and the cadilatic converter. any ideas....


i HAVE BEEN GETTING THE PO316 CODE FOR THE LAST 3 MONTHS. I HAVE FOUND 7 OTHER LINCOLN AVIATOR OWNERS EXPERIENCING THE SAME PROBLEM. BETWEEN THE RANGE OF 40-60 THE TRUCK STUTTERS, STAULS AND RUNS EXTREMELY ROUGH. WE ALL HAVE LAREADY CHANGED THE COILS, COIL PACKS, SPARK PLUGS, FUEL FILTER, THROTTLE SENSOR, CAM SENSOR, CRANK SENSOR AND ARE LEFT WITH THE SAME PROBLEM. I HAVE ALSO HAD 3 LOCAL MECHANIC SHOPS RUN 1 HOUR DIAGNOSTICS ON THE TRUCK AS WELL AS A PERSONAL MECHANIC AND THE PO316 MISFIRE CODE IS VERY VAGUE. IF ANYONE HAS A RESOLUTION TO THIS PROBLEM PLEASE LET ME KNOW.
THANK YOU

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.

Why does my Aviator keep fouling the plugs


POSSIBLE CAUSES FOR SPARK PLUGS FOULING OUT. WEAK SPARK IGNITION SYSTEM - STOP UP AIR FILTER - LEAKING FUEL INJECTORS - FAULTY FUEL PRESSURE REGULATOR WITH LEAING DIAPHRAM.

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?
