my SL began cutting out intermittently at 3k RPM or higher. after seeing other posts on this forum I wasn't surprised to learn that one of the ignition coil packs had gone bad. the dealer replaced the coil pack under CPO warranty. I also had the plugs replaced.

the baby runs like brand new again.

Was it the left bank - driver's side?

Also can you post the part number from dealer invoice?

I believe there was an upgraded part, but don't know the # or when it was upgraded......

Want to compare to the one I had installed in my car....

I had same result......awesome performance......

thanks in advance....

hi abiazis, Yes, it was left bank. The cylinders tripping the CEL were #7 & #9.

The part number = 275-150-07-80
