We have a 2004 Mazdaspeed MX5 turbo. It had minor repair to front bumper at a reputible body shop. They ended up detailing the car and engine compartment. Now when you accellerate throught the gears, its fine, but when you are in the 3000 rpm range the car starts to surge or hesitate. The rpms seem to stay constant, but its like it is loosing power. Its not the clutch. Could they have got water inside something? Would this effect the turbo? Any help would be appreciated!(huh)
