My 99 GT 4.6 2V smokes at idle is it's more blue than white. It smells real rich. But, at high RPM it's fine. I have noticed it using oil. It seems to stumble at 4000 RPMs but clears up around 5000. There no smoke at high RPM. Just hoping to get some ideas.

Thanks
For any help

Usually: white-coolant; blue-oil; black-gas. Usually blue at idle and when taking off at first is valve seals/guides. Yours is weird with the rich smell and blue/white, so I would do a compression check wet and dry.
