Lincoln Ignition Problems...
My friend has an '89 Town car with the 5.0 EFI motor. Recently, it's been developing a bad miss under part throttle. I first thought it was something as simple as a TPS, but after looking into it and testing it, the TPS is fine.
Now, I think it has to do with the ignition system, but I have no experience with the Duraspark II system. When I came to the ignition, I thought it would be an easy cap, rotor, wires, and plugs job. But, the more i think of it, since the car runs great at idle and anything over 1/2 throttle, I think it might have something to do with the spark advance system. Could it be not advancing enough at part throttle? What would be a good way to test the system? I'm afraid all this shuddering will trash the driveline if it keeps being driven!
Thanks for the help!

Mine has the same problem.
I will assume that checking & either cleaning or replacing certain ignition parts will cause it to leave.
Wires along could cause it.
I would check the wires,plugs, & distributor cap contacts before replacing any parts.
I wish I could stand on my legs long enough to do to my all that I mentioned.
