“I own a 2001 Lincoln Navigator with a 5.4l engine. I was on my way to work and was going approx. 15 MPH when I heard a bang coming from the front of the car. At first I thought I had hit something or something was falling off the car. I pulled over to the side of the road and at this time the engine started to run rough. I shut it off and checked under the hood but could not see anything wrong. I thought, after restarting the engine that it might be a bad spark plug. …”
NHTSA complaint #10359981, filed 2010-10, 68,094 miles“Second time the spark plug blew out of the triton 54 head.. Trained tec performed it the first time sert install and worked fine.

Instead they rather blame the techs and the customer.”

Once depressed, idle does not return. Engine RPM stays elevated, dropping only when gears change, then building back up to stiuck RPM. When placed in neutral, engine revolutions increase to almost 5000 RPM; placing vehicle in drive causes RPM to drop to approximately 2200, which is consistent with 70 MPH in drive. Vehicle cannot be stopped unless gearshift is placed in neutral or ignition turned off. …”
