I hope some can help, after the stater motor on my 1.6k giving up, I bought a Brise starter motor. On my last trackday of 2011 my car suddenly developed a misfire during the afternoon session having run all morning no problem.
On returning to the pits and restarting, the starter motor stayed engaged. Could this have been the root cause and have caused the misfire? It seems a bit of a coincidence that the two things happened at a similar (If not the same) time. Could there have been some sort of voltage spike from the engaged starter motor that has damaged something?
Any ideas gratefully received, before starting down the (time consuming and expensive) route of changing every electrical component on the car to trackdown the misfire!!
Thanks
John
