What specificaly is the observation that indacate leanness? the two crude ways to tell if an engine is running lean are a spark plug color inspection, and is the exhaust pipe exit light brown or what... as long as the spark plug is tan in color it is ok. If the plug is white in color you need to enrich the feul air mix. As beatr911 has indicated the only real way to dial in the fuel air mix is with an o2 sencer, air fuel meter. Your dealer should at least do a spark plug check. anything less is neglegent on the dealers part. pulling your spark plug and looking at its color should not take 30 minutes including all the paper work! failing that do it yourself.
