Even if it did then how will you control it? The ECU (if it even had one) may not have any sensor inputs ... if it did I can guarantee that your cars ECU would not recognize them simply because the algorithm (computer program) is written for a 2001 Century

Ok so if it don't have the ecu wud it work ?


It has an ECM and is computer controlled! GM cars 1981 and newer do. But the swap won't work. A 1991 model is OBD I, a 2001 model is OBD II. Completely different computer systems!
