i am working on a 05 silverado 4.3 i had to replace dist. due to a broken screw hole. it ran ok with duct tape to hold the cap down, no codes. replaced with an autozone dist. it dropped right in rotor pointing at same place as old one. the truck acted as if it were out of time, rechecked and rechecked timing same outcome.dropped in a used gm unit it started but gave a p0016 code. this is the first fourm i have done. im out of ideas on this problem

are you positive its not 1 tooth out?

either that or wrong part would be my guess?

Well i am not 100% sure. when i installed it would not line up perfect,posibly one off. i did try to back up one tooth but distributor would'nt sit all the way down. I will go at it again in the AM.
