We just purchased a 2002 Quest with 89K miles. Our 5th nissan in the family. In comparison to our up-for-sale 2000
Buick Century with 136K mi, Nissan's engine is little rougher, louder, and
kind of jerky. Buick's is smooth as a butter. What should I do to make
this go away? Start with spark plugs? I don't know if the dealer has
serviced it except oil change and detailing before the sale. I mean the van runs fine,
but not silky smooth as the Buick. I can tell the difference. Maybe we are just not used to the
new v6? I would also like to replace a fuel filter and hear your recommendations on any other stuff to do. Is there a timing belt or just chain?
So, should I change:
1. spark plugs
2. distributor cap (needed?)
3. fuel filter (should be easy)
4. timing belt (if no chain) - but this would have to be taken in, too complicated
Thanks!
