Unhappy saw filer
starts quick and runs fine until it warms up, 2 or 3 miles. then starts missing and dies. wait 10 or fifteen mins. and it'll go again. but not far.
put on new fuel filter and coil. no help. gas pressure at 32

^^^ tfi will also sometimes leave ignition related codes in the ECM, but TFI is most common for what you describe.

it's really just a translator between the computer, pick up signal, and the coil. the tfi turns the analog pick up signal into a digital signal and sends it back thru PIP to the computer. computer returns over SPOUT with the advanced timing signal, and the TFI controls the coil.
