Patrick -
Try removing, cleaning, and reseating all of your TCU and sensor
connections. The Operator's Manual (Ed. 0 1998 12 01) says that a
blinking orange is due to a failure of a sensor, sensor wiring, TCU, or
airbox leakage. Hopefully your problem will turn out to be the cheapest
of those possibilities!
