Ford recommends changing the spark plugs on my 2004 f150 5. 4 3-valve at 100,000 miles. Mileage was getting close so I tried to change them. Unfortunately Ford did not tell owners that there is a huge problem with the spark plugs breaking-off in the cylinder causing a massive repair bill. Engine had must be removed to take out broken plug. Ford did produce a TSB, but did not inform owners that this routine service should be done by dealer. Upon checking internet, there are scores of reports of the plugs breaking when both owners and dealers attempt the routine maintenance.
Without any warning the v-8 5. 4 engine started missing, dealer in winslow az said they had a lot oftrouble with that engine shooting the spark plugs out. Two of the plugs were loose , one apparently more than the other. Replacing plugs did not help. Some reports of others tell of this going on since before 97. Some with fires. I wonder why this situation has gone on so long and still not fixed.
