My new Saturn VUE 2004 front-wheel drive with V6 3.5L engine seems to be running just fine, but I wonder about the engine: it sounds a bit like a diesel motor when it's idling. It's not noisy at all, but I hear a sort of rhythmic chugga-chugga sound that reminds me of diesel trucks. I was wondering if any other VUE owners have noticed this and if it's normal. Thanks for your help and feedback... Michael
