Ive got a problem with my car missing underload ive taken it to Ford 3-4 times they have replaced the coils, checked the cat, checked fuel pump, did a compression test and still dont know what it is it starts missing at about 3000rpm and wont stop till the gear change. Would anyone have any ideas or know of any good mechanics they may its getting pretty frustrating and costing a bit anything in the Bayswater type area would be handy as I work near there.
