Well, I got my K5 emissions tested on Thur & it barely failed. The mechanic recommended I replace the fuel fliter assembly as it's leaking out fuel & in air. Also recommeded I clean ou the crank case pressure thingy and replace the return lines as they are all leaking fuel out and air in as well. The injectors are also leaking, but that won't affect emissions, so due to expense, they'll have to keep leaking for now. Well, maybe I can get everything fixed this weekend and retest on Monday.
