Hi. My FZJ80 has had a high pitched whistling noise for some time (not when I first bought it). It only occurs on acceleration, in any gear, whether it be light, moderate acceleration or wide open throttle and only above 2.5k rpm (roughly).

I'm thinking it's a vacuum leak somewhere. I have tried listening with a length of hose and tried systematically spraying potential areas with Aerostart.

I've been unsuccessful in remedying the issue (though I did find some other split hoses).

Thanks for your help and time.

Try spraying choke cleaner in different places on intake, if there is aleak there the rpm will change. If yo have cannisters or pwoer brake try there as well.
