Hi guys, I own a 2004 Chevrolet Venture, 3.4L engine with about 58,000 miles on it. This problem occurrs only when I am idlling-- the idle is sort of rough, almost like a small shaking feeling. It's noticeable when setting in the drivers seat, or even when you put your hands on the steering wheel. Do you think all I need are some new spark plugs? Suggestions? Thanks!

These motors are notorious for intake manifold gasket problems. Sounds like it may be there.
Sometimes they leak or burn coolant and or oil, sometimes they will get a vacuum leak, sometimes fluids get mixed from them.

Could be just a tune-up kit that is needed,then again Mr. SW could be right all along.

The reason I'm more inclined to thnk intake gasket is because I have seen so many and with this type of symptom. I doubted plugs because it seems that when I pull out the plugs that have 80,000 on them the gap is still in spec and look decent. They seem to really go downhill after that.
