i did the stupidest thing 2 years ago I bought a distributor From auto zone.
It seems to always be going bad. It has had a code 16 Low resolution pulse. This is my 3rd distributor in 2 years is this because its auto zone junk. Or is there something else causing it. I should have known it was junk when it has a lifetime warranty!!! Any input would help.

 

it probably is the opti, but check the connector and wires to make sure they don't have a break
