I have a 2006 GTX wake board Edition. It is naturally aspirated. It had a check engine light with a 326 code. The ski would only go about 10 MPH. I checked the knock sensor and it was bad (only 1600k ohms and not about 5 meg ohms) I replaced the sensor. Now there is no check engine light but the ski now only gets to about 25 MPH which is about 5000RPM. Is there something that I have to do after replacing the sensor? Thanks.
