Mine did the same thing. Never gave me an error code. Replaced everything from coil, iac, fuel pressure regulator, plug wires, etc., etc. End up being the PIP sensor in the distributor. I tried to replace it but couldn't get the gear off of the shaft. Finally replaced the whole distributor...

Just had a fire start in the A/C evaporator shroud. By the time I got the fire extinguisher it had burned away the shroud as well as the blower motor housing. Happened while driving - no fuses blew. Only thing in the shroud is the blower motor resistor. Can this cause the fire?'96 Bronco 5.8L
