Ok, so the 3.7 in my 'kota is making a werid noise. If I'm holding it at about 40-50, it makes a screaming/screeching noise. I'm guessing a vacuum leak, but does anybody know which hose to check or if it is a different problem?

 

Screaming/screeching sounds more like a bearing. I'd think more of a whistle if it was a vacuum leak.

While it's doing it, does it change in relation to the gas pedal? That would affect the vacuum - floor it and vacuum drops, foot off and vacuum rises.

 

No, it's definetly a Vacuum issue, when i step the throttle up a little, it goes away, and when I drop the throttle a little, it goes away. and it only occurs around the higher speed, lower RPM ranges, like when it shifts into a higher gear and stays at a lower range.
