A few days ago I posted a thread called pops and sputters. Well today I had the chance to work on it a little bit more and here is what I found. 2 and 3 cylinders had fuel on the spark plugs after just a few minutes of running the engine. Cylinder 1 looked OK, but number 4 was like 2 and 3, black and sooty minus the fuel. I did a fuel pressure test and seen I was running on about 85-90psi of fuel pressure. I had this problem already and changed the fuel pump out from a shadow in hopes this would solve the problem. Apperently I was wrong. Any ideas? Please help!
