Recently I had a misfire on my 2010 5.7 on cylinder #1 and found the lifter had went bad causing the camshaft to wear a lobe out, so I pulled the engine and changed it out with a non mds cam and lifters. Put the engine back in, got everything buttoned up and running, then low and behold I had a misfire on #6 at idle only! So I checked and changed everything in the world, talked to all kinds of people trying to find out what the problem was that I was having. Lots of good ideas but still not fixing the problem! So I found what the problem was and I will share it with you guys but I want to see if anyone out there has had the same problem as me? So give me all your thoughts and ideas and I will tell you just how I figured it out and fixed the problem!
