First, I had P0304 misfire cylinder #4, but no other codes. So I changed out the spark plug for cylinder #4 (using an NGK G-Power, which is the same plug that was in there before), and also switched the coil with cylinder 6's coil. Thank god the misfire is on the front bank!
Now my problem is that it's still misfiring, still constant always missing under 1500 rpm or so. But, the CEL isn't coming back on! Runs and feels the exact same as before, but I'm not getting a code now. What takes so long for a misfire code to trigger? The misfire monitor is continuous, so it's always ready, and a misfire severe enough to damage the cat should make it blink immediately!
