Fuel Injection Problems of Lincoln Navigator

A little complex for this little box. Driving in town. Car starter to run really rough, volumes of white smoke out of tail pipe. Check engine light on. Flatbedded car to dealer. Next day learned 2 fuel injectors had jammed on. Dealer repaired. Later in day, dealer explained 2 connecting rods had been bent attempting to compress fluid (gasoline). Ford supplied a short block under warranty. Six months later, volumes of white smoke, rough running, check engine light on. Dealer stated another injector had jammed partially open. Replaced. I asked if they had replaced all eight the initial time. No, Ford wont allow. Will Ford allow this time. No. Letter to Ford 6 weeks ago. Asked Ford to replace the remaining 5 fuel injectors. No answer. Also learned that Ford changed injector valve manufactures for the 2005 model year. Ive also learned Ford has had many, many problems with the injector valves used in 2005. I believe I am now driving a car that has a good likelihood of stranding me and my family in a minnesota winter. Yes, it is still under warranty - but that won't keep us from freezing on a lonely road. Can you do anything to document other cases? can you do anything to help me?.

Accelerator pedal becomes hard to depress whenever temperature is below fifteen degrees f for an extended period. 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. It would appear that conditon relieves after about twenty minutes of driving, consistent with some internal component warming sufficiently to relieve a cold-originated contraction apparently causing binding. Condition returns randomly at somewhat higher temperatures at speed, almost as though responding to wind chill cold. Dealer obeserved conditon in two-day obervation, did not cure probelm, yet released vehicle in unsafe condition. No followup following week; reported to Lincoln customer care, but complaint ignored; no action taken. "we'll investigate" three weeks now.
