heck, could be a few things.If shes gutless and wont go over 70/80 at a push, it could be MAF, try disconnecting and see how she drives. When you say speedo, do you mean the bit where it tells you how many miles you have done?as i thought the speedo was the dial that shows how fast you are going. Limp home mode means its gutless and no oomph...the gal can go a lot faster than that :unsure: as for not starting straight off from cold..not sure on that one as never had that problem
