Question about 2003 Nissan Murano
I have not been using the 91 Octane Fuel. My car now has that knocking sound every time I step on the gas pedal. I have been told to start putting the higher fuel and which I did but I have gone through a full gas tank with that higher fuel and the knock is still there. My question is, will this knocking go away soon as I continue to fill up my tank with the higher octane fuel?
If the knocking did not go away with the higher octane fuel then you may have other problems. A dirty fuel injector oor a misfiring spark plug can also cause knocking in a modern car. A faulty sensor may also be causing the wrong fuel / air mixture in the cylinder... check out the cheapest fixes first.
