Does it appear as soon as there is a problem? Or is there a lag?
Meaning, if a "cylinder misfire" code pops up does it mean it happened right at that moment, or some time in the past? Yesterday morning I had a "P1316 #E8 Misfire Excessive Emissions Fault" I have new plugs and wires. I did nothing but clear the code, and it hasn't reappeared. Is it an old code? Why doesn't it appear every time the motor runs if something is incorrect?
