Ok here is the deal. Yesterday i got a 1999 zl 600 efi, it was just rebuilt and i can't get it to run decent. It starts up first pull and it idles decent with the odd stutter/roughness and if i try to get on it and go, it will go to 5k and anywhere after 5k it is like i shut it off, once it gets below 5k it starts back up. Now i have ohmed out all the important electrical components and everything is in spec. There are two trouble codes, 3 and 6. Now, this is my first efi sled so i hope im missing some easy fix cause we are supposed to be getting 20-30 cm of fresh powder tomorrow! Help me out guys!!
