Failed CA Emissions Test

[Alias137]

When I tested my 86 last year, I went in without doing anything either. After I failed the pre test (I never want to fail a test since you don't get too many chances before you are a gross polluter) I went home and tuned her up. I wish I would have takedn a picture of my rotor. Destroyed beyond belief. I was amazed that the pickup even ran when I pulled the cap. So I replaced it all, went down and easily passed. I wouldn't worry about no cat though, your truck gvw is too much to require one for that year/weight combo. Be sure too that all of your vacuum lines are right. Having one off or in the wrong olace will (or can rather) cause your truck to miss and run on 7 cylinders only. This will fail you for sure, as you're putting all unburnt fuel right out of the tail. You'll know if your missing though- it will idle and run horribly.
