Sorry I need to post mods. I have replaced them before but not this last time,there not but about 6 months old.
And no I have not had comp. test yet. I had bypass box hooked back up on it again today and no surge no miss sounds great but as soon as I hook vp back up it starts surgeing. You can make it surge just by turning on the a/c or letting out on the clutch. The way I understand it is the bypass box elimniate the elec. in the vp and ecm. Everything on the outside of eng. is brand new.
