Guy at the garage told me i should clean the T/B every so often with cleaner and it shouldnt have much problems after that. Its a common problem with the vectras with the T/B getting very dirty and makes the idle control value get a tad bit bumpy. Pretty easy, all you need is a spray bottle cleaner, screw driver and a cloth, oh and some tough fingers 😛 Cleaned it before i went to ChippedUk.
