Mazda for sale keeps going into limp mode / loss of power. I have spent over 800 trying to solve the problem but I don't have the time anymore. Nothing comes up on the diagnostics and 2 mechanics I know have had a look and can't find / fix the problem. It will drive for 15 mins and then lose power. I'm looking for around 2200 or there abouts on offers. I have quite a bit of history and my own papers of work that's been done. 2 keys, 137,000 miles (almost), MOT till Sep 26.
