Two sources tell me the anti-knock sensor is bad. The Nissan dealer says this needs to be replaced ASAP as a faulty sensor can result in engine damage. A very respecte independent mechanic says to leave it alone, no damage will result. What should I do? If it needs to be replaced, can I do it or is this one of those jobs best left to the pros? If I can do it, can you provide 'how to' information? Thanks for your help.
