Brand new truck, got some weird hissing/whistle noise if I barely apply pressure to the gas pedal. Took the truck to Toyota, engineers came out to review and said the noise was from the stock air box, it's the sound of air being sucked in. They reported that if I switched to a CAI, the noise will go away. WELL.... $400 later and a few extra horses, the noise is still there. WTF! Anyone else have this problem?
Need to drive with radio off, cruise at any speed and then slightly apply pressure to give it gas, just enough to raise your RPM's. Quite annoying if you drive sometimes with the radio off... I know I know.... leave the radio on but we all need some quite time especially after a hard days work.
