High pitch noise at highway speeds
It's been a while since I posted here but was hoping someone could help me out. I drive back and forth from school certain weekends to go back and work to stay current with my summer/break job. When driving over 65 mph on the highway I hear a high pictched screeching noise that will start and stop every 10-15 seconds. It goes on for about 5 seconds then stops for 10. It also happens when I'm accelerating over 60 mph. I've ruled out that it was my K&N intake because I took it off to see if the noise is there and it still is, just a little softer. Is there some connection that you guys know would cycle like this that I could check? I'm thinking it is something along the lines of the intake because the sound is softer but still present with the factory intake re-installed. Any help or suggestions would be greatly appreciated.
