Good afternoon, I have a Peugeot 307 SW, with a power of 136 hp, and 16 months ago this problem of lack of potenti appeared for the first time, as I am now working in Morocco, it takes it to a workshop and they told me that the problem was solved by changing the turbo, it changed to a 2nd hand and in principle it returned to work well, but now the lack of power reappears. What do I do with him? The car is now 6 years old and 150,000 km .. From the fault of the power I have had several breakdowns since the lack of power appeared, one of them was that the car was pulling.
Please guide me where the failure can be.
Thank you
