Hi guys,

firstly , 2006 2.2 direct vectra

When i accelerate low down, i get a really weird noise thats sort of squeaky, kinda like a squeaky belt but couldnt say that that is the noise.

Really baffled by it, to clarify, it would happen for example if i was in 4th gear and my speed reduced to 20 and i tried to accelerate anything harder than gently. Or 2nd gear when i should be in first. Sounds like it is really struggling but doesn affect how it pulls.

Any ideas?
