To replace the TFI (Thick Film Ignition) module on a 1987 Ford Ranger, first disconnect the negative battery terminal to ensure safety. Remove the distributor cap to access the TFI module, which is typically mounted on the side of the distributor. Disconnect the electrical connectors and unbolt the module, then replace it with the new TFI module, reattach the connectors, and reassemble the distributor cap. Finally, reconnect the negative battery terminal and start the vehicle to ensure proper operation.
Check the TFI module. It is located on the distributor.

I have a 1992 Tempo that was stalling all the time after it warmed up. I found out there was a class-action lawsuit against Ford for defective design/location of the TFI modules because they malfunction when they get hot. By court order, Ford extended the warranty on these TFI modules to 100,000 miles, regardless of age or resale. My local Ford Dealer ordered a replacement from the Obsolete Parts department at Ford and installed it all at no charge.

If it only happens after the car warms up, it may be the TFI module. I have a 1992 Tempo that was stalling all the time after it warmed up.

You dont if its fuel injected. They all use the TFI system and no adjustment is available .
On the back of the distributor which is located on the top of the engine rear center, the ignition module (or TFI module as ford calls it) has two screws bolting it to the distributor and one electrical connection, when you replace this you MUST use di-electric grease when installing the new one or it will fail due to excessive heat created by the engine.
YES! If you have tried a major tune up to include: spark plugs, distributor cap , rotor, wires, and fuel pump and the truck still idles rough and stalls at stop signs then it is the TFI ignition modual located on the side of the distributor.
