Hi everyone ,I have a 2004 150hp Johnson
..i can't seam to figure out the problem ..when I go over 4000 rpm the check engine goes off ,I then throttle back down to idol and the light clears ...i change a bunch of stuff .I'll list what changed below
New vro pump
New pickup tube
New gas lines
New anti siphon valve
New water fuel seporateor
Vent and on gas tanks clear
Compression on all cylinders is good (via mechanic)
Any ideas ?
