I'm having the very same problem with mine and have been told it's the catalytic converter that needs to be replaced. Apparently it becomes clogged and the oxygen can't flow through properly. I hope this will at least give you a lead of some sort. Another thing that was mentioned that I am looking into now is a 'map' sensor???? Good luck!!
Probably a bad head gasket.
Right behind the battery in the engin department... i had a similar problem
The bulb is falty, replace it and it should cure your problem.
There is a ground problem, either with the ground wire or in the socket.
could be the magnetic pick-up in your distributor, I replaced mine and it solved the problem.
Assuming it is screeching in the area of the belt and pulleys, my problem was that the belt tensioner had seized and needed to be replaced. Noise problem was solved.
Had that same problem on my 93 the tensioner wore out. had to have it replaced.
i had the same fault with my 1996 dodge Plymouth, 3.3 litre engine. i replaced the crankshaft sensor and viola problem was resolved.
If the pedal firms up after pumping a few times, its probably air in the lines. Bleed the brakes. If this does not solve the problem look for leaks and record your symptoms in detail to tell your mechanic and go see him soon!
Not sure if its the same design, but on my 1998 Continental the jerking was caused originally by a few of the individual coils going out. These are found on my vehicle right on the plug that attaches to the spark plug. That is, one sits right on top of each plug. Replacing these (about $65 each as I recall) was pretty simple. Of course, later on a similar jerking occurred which turned out to be the transmission. Ford replaced it. Hopefully, your problem stems only from the mini-ignition coils.
There are a couple of reasons why you car is jerking when you are going below 60. It could be the result of a problem with your transmission, or your fuel pump could be going.
You need to find out what is causing the jerking before replacing parts. A scan of the computer can reveal the problem and most auto parts store will do this for free.
