i have a current thread about my truck not running right, but today i removed my fuel injectors again to check to see if the o-rings were good, i replaced all 16, 8 washers, and 8 pintle tips, re-installed them, and my truck seems to run even worse than before, i checked all connections and they were good and tight, i used di-electric grease on all connectors....any ideas if this could be a sourcce of my problems???
