No, that's not a banana in my pants.
I have been adding a bottle of the Amsoil PI to my fuel tank at every oil change for a few years now.
I recently started getting a CEL for the knock sensors. I reset it and the code would come back a day or two later. I was dreading changing the knock sensors, but I was getting ready to order new knock sensors from Rock auto. Then I added a bottle of PI to my gas tank, part of my normal maintenance. And I reset the CEL around the same time. (Since I have a code reader, I just keep resetting it because I hate seeing it lit up on my cluster
) I was surprised several days later when the code had not returned. I was like WTF?
Then I thought back and remembered that I added a bottle of PI the day before I reset the CEL, and then I realized that the PI must have done something to make the engine run smoother so that the knock sensors are not triggered. Its been well over a month now and the knock sensor code has not returned .
So if you ever get a knock sensor code, I would HIGHLY recommend you try a bottle of PI before diving in and replacing the knock sensors. And I would also like to thank Nick for getting me hooked on this stuff. He sent me a free bottle of it years ago and once I tried it I was hooked when I realized how much it actually improved the performance of my engine, and my fuel mileage as well.
