2008 Seadoo Gtx knock sensor

[Lrway]

Hello guys it’s me again. As I have posted previously about the knock sensor on my Seadoo gtx 155 2008 knock sensor, I have replaced the knock sensor with an oem knock sensor and still have the same issues. I have checked the wiring harness and the Oems are good to go, but I still get the P0326 code when high rpms are given. I put some sea foam in the tank with a full tank of ethanol free fuel and received the code much less but when the tank was empty and filled with pure ethanol free I revived the code appeared almost every time I passed 7k rpm. I have almost given up trying to fix this issue. Could it be a coil pack or spark plug issue at this point. Any idea would be appreciated! The ski has about 296 hours and the compression is 150 across all 3. Thanks in advance!
