I did the compression test on my 94 5.0the other day with the engine cold and I got poor results. #1, 85 #2, 90, #3, 90 #4, 90 #5, 120 #6, 95 #7 125 #8, 120.
After doing some research I found out you are supposed to do this test with the engine completley warmed up and with all the plugs out. So I redid the test and was very happy. #1, 135 #2, 140 #3, 135 #4 150 #5, 140 #6, 135 #7, 140 #8, 140.
I am super happy with the results. I still have a super smoke issue. I dont know where to go from here.
