MR2 Owners Club

My Mk3 MR2 has been making a squeaking noise whilst accelerating, it does not seem to make the noise whilst driving at a constant speed. I have replaced the belt, belt tensioner, and idler pulley in order to try and fix this issue however it is still persisting. Does anyone have any ideas on how to fix this? Many thanks.

I have added some videos in the replies.

Would need more info to even make a guess, could you record it ? does it seem related to engine speed or wheel speed ?

I can try and get a video of it, it seems to be related to engine speed as the noise can be heard when revving the car at a standstill, I think it is originating from the drive belt system as it does not make the noise when I rev the car with the belt removed.

Alternator?

Here are some videos of the noise that it is making if it helps:

Did you ever fix this? Did you find out what was wrong? My MR2 is making this exact noise and occasionally makes a very loud screech and won't accelerate.
