When driving my evo 9 at a steady throttle I keep getting this misfire that I can see on my wide band. When I let off the throttle and step back into it it will go full lean then rich and back to 14.9. So compression test was the same as when I bought the car. I changed to plugs and wires. I haven't changed the coils yet because I'm running okada projects. And I haven't done a leak down check yet. But when I pulled the timing cover there was bunch of play between the two cams. I have read that this can be Normal. But is this the case with the evo 9. Any help would be great !!!

Thanks
