Default Re: MSD ignition unit

Before buying the multiple spark coils please read this.

I purchased the MSD 82478 8-coil kit a month ago.

After buying it, and after reading this thread, I realize that I should have purchased the 82468 kit, which would have fitted the H2 without the need to make some minor modifications, but I understand that the coils are the same, it is just the housing that changes.

When I fitted the coils I had misfire problems, and the car was reporting the PO300 (multiple missfire) and the PO353 (faulty coil #3) codes. After swapping the coil at position 3 for an original coil, I was still getting the same codes.

I called MSD support, and talked with Basilio Chavez. He suggested that I try using less coils on each bank, as he claimed that there could be a problem with the power lines. After trying this (2 MSD coils on each side), I had the same problem. Talked again to him today, and he says he will talk with his design engineers and that we should talk again tomorrow.

I believe that there is some incompatibility here, and I would not buy them until this has been sorted out.

Has anyone else fitted these coils to the H2? Mine is a 2005-model H2.
