I removed the egr and installed a blockoff plate (same before & after) I removed the vac line to the canister (no change). I have not tried the the crank sensor and it is from the previous engine. I thought these were either good or bad?? I am going to have to look up your procedure and try to reset the cam sensor. I have been through 3 sets of plugs ( annual maintenance) with no change. again this problem existed with my last engine and now this new engine. the only time I see the BLM's at 128 is when letting off while cruising.
