i did, the way the sensor works, however, is measuring the misfire rate over a period of two LD car trips. What i mean to say, is thouhg its gone now if the misfires, (if thats the cause) are still occuring, than the code will be back. i just finished my first, and will finish my second at 5:15 CST. ill know then, i think this is just going to be an excuse to tune my car finally.
