V12 Misfire
Hello, I am new here. I have a 2006 S65. It starts and runs fine and drives good using moderate throttle. When i push down harder, I now get a check engine light and some of the cylinders go away.
I ran a diagnostic and got this: P2050 Misfiring, Damage TWC (P0300) stored P2052 Misfiring Cylinder 5 Damage to TWC (P0305) current and stored P2054 Misfiring Cylinder 6 Damage to TWC (P0306) stored I clear the faults and the car runs normally as before. I have ran it several times, sometimes I get a cylinder 4 fault as well. When I come back it is not firing right for sure, but it clears up when I clear the faults. The car has 65k miles and has always ran great. I only drive the car 20 miles per week or so. Any help on this would be appreciated. |
I have a s600 same year and I was told over the weekend that I needed to new plugs and they also suggested to change the coil packs, $5100 total costs and $700 was labor.
|
I replaced the plugs hoping that was all, but it turned out to be the right coil. I replaced that and the car runs great now.
