Answer?
Just found this information: "The problem is caused by the thick film ignition ("TFI") modules, a key ignition-system component that Ford installed in more than 22 million vehicles it manufactured and sold in the 1983 through 1995 mode years. The TFI module regulates the electrical current that fires the air-fuel mixture in each of the engine’s cylinders. To reduce costs, Ford installed the TFI on the distributor, one of the hottest locations under the hood. But because the TFI module is sensitive to heat, its mounting location creates an inordinate propensity for the TFI module to fail due to thermal stress. Making the problem even more insidious is its phantom nature. A TFI module can fail on an intermittent basis when hot, then function again when the engine cools, without leaving a trace of physical evidence that the TFI module had failed."
Sounds awfully familiar. Wonder if they came up with a retrofit to solve the issue.
