225 Optimax idle problem

[N Russell]

I have a 1999 to 25 mercury OptiMaxx, very rough idling. I tested all the cylinders by removing power wire at injector number two hole is the problem I swapped the plug,boot, and coil to another one still a problem The problem stayed at number two. I tried a new injector And still Have the problem. Any ideas?

Did you do a compression test and or leak down test?

Also, I think you will get better results and more answers if you delete this post and re-post it in the Mercury Outboard forum here on Iboats.
