Mark, I have changed all the sparkplugs(that`s not easy the car runs on Propane and almost the whole LPG-systeem had to be removed) and now the engine is running perfect again , no stalls and no warning lights came on, sparkplugs had done almost 100.000 miles,
thanks again for your help,

You did not find a bad coil? I'm a bit surprised. There is something about this engine's computer that really gets confused when the spark plugs and/or coils mess up. I tried to talk to the dealer's service manager about this and he denied that there was such a problem that he was aware of. In spite of that, he did finally suggest I change all spark plugs and coils "just in case" after I pressed him with the information I'd gathered about other vehicles I knew of with the same symptoms. I changed all plugs and the one coil that looked bad and seemed to come up the most often on the check engine analizer code and fixed the problem. Strange that I know of many others with this same exact symptoms and problems but the dealer says he's "...never heard of it." Why don't they just admit they have a problem and tell us what to do? Is Lincoln/Ford afraid to admit that this problem is common? Why?

If they admit that there is a problem, we will be after them to issue a recall. I have had issues with the coil on plug design. To me, the 4 - coil pack with the conventional spark plug wires was more relaible. With the coil on plug design, when the engine misfire causes the car to buck and jerk, the computer may or may not indicate which cylinder is misfiring.

i have a 2001 linconln town car and it has just started doing what i hate the most out of car, when im crusing and i want to increase speed by just 1 or 2 miles it starts jerking as i just show the foot to the gas pedal, it only does it when i very very lighly step on the gas to increase speed by 1 or 2 miles, i have tried changing the gas from BP 93 to Marathon 93 and still the same , i added lucas fuel injector cleaner and still the same, does anyone have an idea what it could be? Im not sure if its a fuel injector problem, or a spark plug problem or a coil, i dont know, first time i own a lincoln and im already disappointed, the car only has 38000 miles very clean, but this is really getting to me

The engine is probably misfiring underload because all of the spark plugs and coils are not firing as they should. It is not uncommon for the Ford 4.6 engine to start misfiring at 30000+ miles. Does your engine service light come on? In most instances, all of the plugs and coils do not need changing at one time, just the one or two that are misfiring. If your engine service light is not coming on, change the plugs and coils in this order: 1, 4, 5, and 8. For some reason, the plugs near the very ends of the block are the first to start misfireing. Replace these, one at a time. That is, replace the coil and plug in cylinder 1, then drive the car. This may be the only one that needs to be replaced. I hope that your opinion of the car will change for the better. You should be getting about 30 mpg. With basic maintenance, the car should give you about 140,000 miles and 7 years of trouble free driving.

I have had a 2000 and have a 2002 and have never gotten anywhere near 30 mpg. Best on the 2000 was around 24 and my 2002 w/dual exhaust has been a little over 26. I have done the other things like keep good tires properly inflated and slow starts,easy accelerations, and use cruise on the interstates. I seem to get good mileage around 55-60 and 85+. The time I got over 26, I was driving on interstate running 85 mph. I do not use the higher octane due to the recommendation from the LM dealer. I was told it is a waste of money.
Both engines started to periodically not crank or idle around 65K. The engine will run but will not idle. Drive it for a couple of minutes. It will crank and idle fine from then on.

I have a 2000 Towncar. I get 30 mph on the freeway if I stay at 55. At 65-70 I get 25-27 mph. I get 19.4 mph average with about 70% intown driving, 30% freeway driving. My car has about 83,000 miles and runs great on regular gas now that I've found and repaired the coil problems.

i wanna thank you much for your help, i love the looks of this car and will like to keep it but i wont if i dont find the solution to this problem, i have removed all spark plugs to inspect and they all look good, i noticed the car started doing that after i rammed the engine up preety good trying to impress a coworker that was behind me in a mustang i took it up to like 80 to 90 mph in short distance, it usually does it around 40 mph and like i said only when i hit the gas very very lightly it jerks preety bad it does feel like a misfire and no i have no check engine light, is there a way to check the coils for misfire, i was told that if it was the coils i would have a check engine light but i dont have one, do u think is more of a coil spark plug problem than a fuel injector problem? i checked the auto part i can get one coil for like $58 bucks and e-bay has a set of all 8 for $100 after market new ones, what do u think. i also want to mention that i also have a 1997 lincoln continental now out of service due to a bad transmission with the same excact problem, on that one i changed the spark plugs and all wires and i stiil had the same problem all the way until the tranny went out, but now im concern about the town car i just thought i meantion that, it seems like the problems i hate the most of car have follwed me with this town car taht i have only owed for 11 months
