I installed the K&N FIPK intake and it worked fine for a month and a half in the city then when i hit the highway recently to florida from va, I noticed my temperature gauge was fluctuating rapidly b/t the half way mark where it should be, and zero (or low temp) it would shoot from the bottom to the mid section, stay there for a bit, fall back down, flicker up a bit but never go above the half way temp degree. It would also drop for distances of 20-30 miles.
I know the sensor is relocated during the process so am not sure if it was affected but why only during highway use? Anyone else have this problem?
Nissan dealership said could be a ground issue but it would cost 75 just to look at it and if it didnt occur at that point in time i would just be throwing my money away b/c they wouldnt be able to do anything.
Also, i was averaging 15 mpg on the highway at 70-75 mph, sometimes 13 and I only have the 2001 non supercharged engine. i dont think that the k&n helped. of course i have 31's... anyone else have 31's and k&n? and what are you experiences with that... alright, lots of questions, hoping for answers. thanks guys
