Engine Mechanical problem
1997 Nissan Altima 4 cyl Automatic 91000 miles
I am not sure what to do. The knock sensor code has come up a few times after clearing it. I have recently, within the last yr, replaced the OXY sensor and MAF. The car seems to drive fine, but I don't want to take the chance and have the engine blow/burn out, whatever can happen. When I turn the car on the engine seems to rattle but calms as I continue to drive, but it has done this for a while. The knock sensor has only come up last 2 months. It will cost me 300 to replace it and I can afford it, but do I need to do it? I have been hit fixing a lot on this car within the last yr, but I want it to last a few more yrs if possible. I only have 90k miles on it. Any advice would be great. Thank you for taking the time to look and comment.
