what problems do the plugs give i just put in P+2's today . there from bosch too . how much different can they be. also i noticed that when i changed them . plugs 1+2 (starting from the back ) were wet with oil . now i forgot to remove the tops on my plugs
and didnt know i had to untill i walked to three auto stores to find wires thinking that the old ones were no good and at the last store there i asked and he told me that i had to.
i never had a bmw so all this is knew to me . my maxima i had P+4 in the mnever nsrewed tops . anyway does this mean i have tomuch oil in motor and would this hurt my motor. car was sitting for two years before i bought it . i plan on changing it next week.thanks
