I have a Nissan Maxima with 94K miles on it. About a month ago the service engine light came on. I took it to the local mechanic who checked the car and suggested I replace the battery. Couple of hours after leaving the garage the light came on again. This time he suggested that I replace all 6-coils for a ridiculous price of 600$. After some research online and sharing experiences with other Nissan Maxima owners, I finally acquiesced and had the coils replaced. One day after leaving the garage, the light came on again.
Now he showed me a copy of the TSB and suggested 'Check and replace wiring harness'. Approx damage $1200. There is no way I am gonna shell out that much dough for this car. Any suggestion guys/gals?
