Hello, New to the site and having trouble with my 2000 Eclipse with 3.0 with 78k original miles. Started it up the other day and noticed like lifter noise and not just in one area but both sides. Pulled codes P300, 0455,0340 and 0335.. Wondering if anyone has has this problem that can share. I just don't believe that lifter/valve just be loose sitting. Any Help Greatly appreciated.
