With the HC jumping around that much it has got an issue somewhere. Check the valve adjustment (still the only thing you messed with since it passed the sniffer). Set the timing 2° retarded from the factory settings, it will be within tolerance for Cali and it will help but not fix the bigger problem. Throw an O2 sensor at it if you have not already, they get funky with a lot of miles on them and if you didn't change it out who knows how old it is. Alcohol is oxygen bearing (the reason they like it for emission in gas) and will help, and do not put acetone in fuel EVER it will cause detonation and kill the engien like now! Acetone works as a starting fluid but it is still a bad idea.

Thanks, I'm going to readjust the valves tomorrow, the day I originally did it was 105 degrees in the shade and I was hot and tired from working with a cheap piece of crap spring compressor while changing the valve seals, I may have rushed through the process in order to get to an icy beer faster! I will take my time next time. I will stay away from the acetone. Someone mentioned using some Restore engine treatment, I may even throw in a can, after all Restore is an overhaul in a can! (sarcasm) thanks for the suggestions, I'm going to spend the day on it checking everything I can. I am so glad I don't have to ever smog my trucks! Thanks again!
