F250 Superduty Air sound?
I have a 99 F250 7.3 that will make a sound like rushing air coming from the exhaust. When idling in neutral and the air sound happens, I can press my accelerator or brake and the air stops.
When driving, it happens when I reach cruising speed and again, I can either accelerate or decelerate and the air noise stops. I don't mean just a little air, I mean a lot of air. also when driving and the air sound starts a reduction of power also is felt.
I appreciate any and all info. you give that will help fix this problem.
