I assume our Grenadiers have the gen 3 b58?

This is my understanding of the generations.
Gen 1, original B58
Gen 2, otherwise known as the B58TU (technical upgrade) This is in the Grenadier.
Gen 3, or B58TU2. This one has both direct and port fuel injection. This is the problem child.
There are also variations within the generations I.e. high and low power versions.
