My 2000 psd 350 4wd upon start up in the cooler weather is making a shutter type noise when idling! Sounds to me like the waste gate maybe open and closing! I assumed this was maybe a cold start feature to help warm the motor or something, but now seems to be getting more frequent! Seems like it is affecting the low end boost just before or just after a shift (auto tranny)! Also when idling, when it starts to shutter, I can touch the brake pedal or accelerator and make it clear up for a while! What is causing this? I would like to fix it before it escalates! Thanks guys!
