I own a 2005 1500 with a 4.7 magnum. Lately Iv decided to buy a cold air intake for it. So I removed the factory intake, and fitted on the new one. My problem is that every time I'm on the highway or just cruising I hear a whistle , it only happens when moving and the RPMs are between 1000 and 3000. it only starts to whistle when the pedal is 1/4 pushed down, the sound fluctuates with the pedals angle, if I push the pedal farther than it will go away, or if a let off the gas. Its not just a slight whistle either you can hear it over the radio. Iv cleaned the throttle body and around the intake really good. any ideas? Could the old intake cover up that sound? Also the weather around here is about 15F.
It even does it with no intake on it.
Many thanks Josh.
