{"text":"Please Help! The Truck makes Whistling/ Sqealing sound while accelerating loaded or not Loaded. It goes away when I take the foot of the accelerator. The more the rpm the louder the sound. This Morning when I started driving it was also smoking from the exhaust pipe while driving. It came from undeothe Truck but went away after 10 minutes. The power is good. I don’t feel any difference in the power while accelerating. With engine break on and foot off the accelerator it makes the noise but when I shut the engine break off and take my foot of the accelerator the sound goes away.It all started after I heard a load POP Sound.","pics":"[]","canComment":true}
