Hello everyone, I have a 1993 Sedan Deville with approx 90K miles on it. It's a fwd 8 cyl. The car hasan error code 38 (MAT Sensor is low). I've changed the MAT sensor and the factory plug for it and tried to clear out the code. Whenver I try to clear the code with my OBD unit, the car hesitates, the engine trouble code light blinks and comes right back on. Any ideas what else the problem could be that's causing the code to stay on and not clear? Thanks.
