I started the car up on Saturday morning, went and picked up my girlfriend and then we jumped on the freeway to go to San Louis Obispo and I live in Huntington Beach so that makes for about a 3-4 hour drive. Right when I hit 70 mph a LOUD squeal/wining/grinding noise started. I immediately let off the gas and checked all my gauges to make sure they were all in the right spot. Everything was good and when I got below 70 the noise stopped. We were like Hmmmmm that is weird. I just got my car serviced about 2 weeks ago so I have no idea. I started on the throttle again because the noise stopped, right when I hit 75 the noise started up again, then it would go away when I got under 75. It kind of sounds like a pulley because I have had pulley's go out but they didn't sound this bad. I pulled over and pulled into a parking lot and popped the hood. All the belts looked good and at idle there was no indication of them looking like they were bad or sounding bad. I had my gf rev the throttle a little and hold it at high but not too high of a rpm. Everything looked good. I told her if the noise happens again we are driving home.
We got back on the freeway and got to 75 mph and no noise. I went up to 80 and still no noise. We continued to drive and about 15 min before we got to where we needed the noise started up. It was doing it at all speeds. I have no idea why it started and no idea why it stopped. I would like to fix the problem but I am at a loss. On the way home it did it for about 5 min then it did not do it again.
Any ideas to what it is and how to fix it?
ps. I dont have intake or any engine upgrades.
