    P0300 and P0302 With new long block 1996 K3500 5.7l

    I have been having a lot of problems with my 1996 K3500 5.7l The truck has about 220K miles on it. I recently had problems with it running very rough. I found out I had low compression on two cylinders, So I decided to get a new Long Block. I replaced a lot of other parts with it. -Blackbear...
