NOTE
FOLLOW THIS TSB PROCEDURE ONLY IF THERE ARE NO SPECIFIC MISFIRE TSBs/SSMs RELEASED FOR THE VEHICLE SYMPTOM BEING
EXPERIENCED. ISSUEnApproximately 50% of coil on plug (COP) coils returned for warranty do not have a problem.
ACTION The misfiring cylinder must be identified through Self-Test misfire codes or through WDS Power Balance. Rule out base engine problems, rule out fuel problems, and then look at ignition problems (be sure to rule out coil primary circuit issues).
Once the above steps have been completed, and the issue is in the secondary part of the ignition system, the oscilloscope procedure outlined in this TSB can isolate the difference between a coil or spark plug problem.

Some 2003-2004 Lincoln Navigator retractable running boards may exhibit false reversal, partial deployment or retraction and/or jerky/noisy operation. This may be due to mechanical binding or damage to running board deployment mechanisms. ACTION Verify there are no hidden debris in the running board tracks that may cause the condition. Clean the running board tracks with a high pressure washer if available and test the system again. If the condition is not corrected follow normal Workshop Manual diagnostics. If the condition continues refer to the Service Procedure for
component testing and replacement.

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.

FORD: 2005 Mustang 2004-2005 F-150 2005 Expedition, F-250, F-350 This article supersedes TSB 05-15-8 to update the Service Procedure. ISSUE Some vehicles equipped with a 4.6L 3-valve or 5.4L 3-valve engine may exhibit a ticking and/or knocking noise after reaching normal operating temperature. The noise may be described as “ticks”, “taps”, “knocks”, or “thumps”. In some cases the noise may be a normal characteristic of these engines. In other cases the noise may require further investigation. Sorting out and defining the noise as reported by the customer is important to successfully diagnose and/or repair the condition. ACTION Before starting diagnosis, it is critical to determine the specific engine noise the customer is concerned with. The customer should be interviewed to get their detailed perception and description of the noise, and to determine if the noise occurs at idle or above idle speed, and if the engine is cold, hot, or both. Attempt to duplicate the noise, and determine the source of the symptom. Refer to the following Service Procedure to help determine the source of the noise and if a repair is needed.
