From the information you posted, it is difficult to understand the issue.
Allow me to try and rephrase, please confirm or let me know if I totally missed it:
You've had a misfire forever and that you address every issue promptly. This was confusing to me.
You say the misfire is nothing and yet you say people tell you that your engine is bad. That seems like two very different feelings on that misfire.
The reason you are posting is the traction control and abs lights came on and now it feels like the power steering and supercharger aren't working properly.
ABS/Traction usually isn't related to a misfire. However each of those can reduce power depending upon the fault.
I'd start off by popping by the auto parts place and getting a free read of the codes, then pop back on here and post the codes and the descriptions of them. That would help us desktop diagnose it much better for you.
