Hi, when I change gear my car struggles to regain power and chugs like it might stall which it hasn't yet but I think it would if I didn't rev. Also its really struggling to pick up speed like when on a carriageway can takes several minutes to get past 50mph then very slowly get above that.
Hope u have an idea what it could be and if expensive to put right.
Thanks for your time.
