When I crank the motor up it will idle fine. When put into gear sounds like there is a spark problem or fuel starvation problem. engine is fresh out of break in, and skips between 1000-1200 rpms. any other rpm up till 4000 it runs fine. When the engine is run over 4000 rpms, the engine sounds like it bogs down. No check engine light. Fresh set of plugs, indexed and gapped. compression checked out fine also. Anybody got any ideas? Last month I sent the EMM in to DFI to get rebuilt and worked fine for about a month. then this problem happened. Any information would be great. Thanks
