2002 Winstar , code P305, Used regular electric repair scope to scope cylinder 5 using 5 v/div, 0.5 mil/sec with 10X probe and got the pattern included. It does not look like anything I have seen on line. Can anyone diagnose this pattern. Engine runs rough at idle, have done the usual things, replaced plugs, wires. coil, injectors and gaskets. Fuel pressure 32 #, cylinder 5 & 6 compression check, 120 #. This same pattern is on cyl. 4, 5, 6.
