Mazda 6 chokes under 3000 rpm
I would like to buy a 2004 Mazda 6 from someone, but they say there is a problem they can\’t figure out and that is why the price is low. the car must be ran at 3000 rpm any lower and the engine chokes. Is this a symptom of a potentially large issue or can it be fixed with minor work? Thank you for your help.
