Dropping Revs

[MazzaR26]

After i've been driving around in my valver for a while, anywhere between 2nd and 5th gear usually around 3k mark the revs will suddenly drop then rise then drop even lower. The car does feel like its going to stall but when i put my foot down further i seem to drive through it and everything is fine again????

Please help. Cheers Mario
