Hello all
I have a 150 EFI 1999 model that runs rough at idle, I have checked compression and they are all at 120 psi I have also installed new plugs, Also I was wondering what the mix of oil is because it is on a 19 Silver King and no room for the Oil reservoir, so that is the way it was built, I purchased from the original owner. As you throttle up it runs a very smooth and sounds awesome. I was told when I purchased it a low fuel pressure pump was needed?? I was told by someone else I could count the blinks from the computer it has when key is on if there is a code?? Any Ideas thank you in advance.
