06 X3 misfires

When I accellerate to merge etc.the engine sounds good till just before it shifts from 3rd to 4th gear (auto trans.).Then it seems to mis fire a bit until it shifts.I put in a bottle of seafoam,and have just replaced the plugs .Plug #2 had oil all over it ,even up the sides of it.
Cleaned up the oil & installed new plug ,but car still misfires with hard accelleration at about 4000 3rd gear.With reving in park or regular runs good.What could it be???
Car is an 06 3.0 with 86k.miles (car orig.from USA)
