If the CEL does not go away can I defeat it some how? What are my options? Someone said something about using a P28 ECU. Does have a 97-01 Lude running a P28? Because if that's the case I have an extra P28 laying around as well as a first gen B16A ECU (forget the code). But won't that throw a code for lack of the knock sensor if I use the P28? Also, are the fuel maps sufficient for an H22? Will the 02 simulator fix this CEL? Can Friggin remove the bulb to the CEL from the cluster?
