I have a 94 GSR...96 Gsr ecu...i am getting a code 23 and 54...i looked at the obd2 si code chart and it said knock sensor code and crankshaft speed sensor code...i dont know if gsr's are the same as si's but does a gsr just have a knock sensor and a crank fluck. speed sensor? i think the code 23 may be a vtec code but i only have the ob1 helms book....
