Hey gang its me Don the man that started this hole topic, sorry I didn't get back into replying fast enough, work keeps me a tad busy at times, but when I can break free occasionaly I will write.
Anyways, Dave I had the same problem as you, I got a 2000 black & tan SVT only 12,000 on oDo though. I still have a warranty but I was curious to know what was wrong with my Tour. Well in the end, and after 10 days at the dealer on two occasions for the same problem (the jerking), problem was resolved. On the first attempt they replaced all six plugs and the ignition coil assembly, thinking it was an elec problem but obviously it wasnt. The 2nd attempt they replaced the (in tank FUEL PUMP), a faulty relay, air intake, and throttle body (the last because of complaints of throttle hang). I'm happy to say thus far problem resolved and purring like a tiger (seems faster to although I think its psychological), but certainly sounds great!!!
I have other problems as well especially with water leaks, 4 different kinds in fact, in the trunk(twice), fog lights(3 times), tail lights, and sunroof/headliner in cabin. I love the space and performance of the car but frankly 26 days out of service in one year and I can almost garantee more days to come cant keep me on the Ford bandwagon for long. I am currently in the process of lemoning the car, dont know if i can go through with it though I love the machine (other alternatives though are jap cars only, altima 3.5se, impreza WRX, or mazd mp3 (with jax racing aftermarket S/C), but will see.
I hope all this usefull info makes you feel a little better about your Tour. I'll get back to your replies not with speed but I will get back, see you later and keep cruising @ 100mph!!!!!!
