HELP!! VSC TRAC, VSC OFF and CEL ON!!
 

started a year ago...took my 2006 T4R in for a tune up and within 2 days the CEL, VSC TRAC and VSCoff lights came on. The codes that keep coming up are a misfire in cylinder 6...we have had the 2 upstream o2 sensors replaced because they said they were only working at 50% as well as a new plug and coil on cylinder 6...after SEVERAL times going back to the same place and after all of the work that has been done the lights will be off for a few weeks, and then come back on again. Any ideas?? I would hate to drive it and cause more damage, and I have already put a TON of money into the car w/o getting the problem solved. Pls help!!!

I have this same problem!! So if anyone can help, please let me know as well. Thanks :)
