    Well mines lost most of the flat spots now anyway, had this really annoying one at 4k which has since gone since I pulled out the airbox. So now it revs freely throughout the rev range.

    I have just acquired a 12 month old 1.8 VVT which has exactly this symptom. Significant flat spot when pulling away and changing from 1st to 2nd.

    Has anyone come up with a fix?

    Thanks

    Nick.
