I just bought my 3rd Tundra this past weekend (an 04 DC, I have previously had an 00 and an 02 all 4x4 V-8's) and really dont like the way the engine sounds on a cold start. My dad had an 01 that he bought new and had the same complaint with this sound the day he picked it up. When you start the truck on a cold day, it idles fine, but as soon as you put it in gear, the engine gets real noisy. You would sware this thing was a diesel if you didnt know any better!! Has anyone else noticed this terrible sound? It sounds like a rattle in the engine, but does it only while in gear, not in 'park' or 'neutral'.
