How fix code po 171 Volvo V70 T5
Hello
I have a Volvo 98 turbo v70 T5 with 135K miles. It was running fine and smooth, suddenly stop as if it doesn’t have gasoline, I take it with my friend mechanic, we scan and check it, and we replaced the fuel pump, fuel relay and filter. It has the engine light on and the code read PO171 bank running too lean MAF. I changed the MAF sensor and it hasn't changed anything (If is unplugged the sensor, the car start and run with a strong smell of ammonia, but if I plugged the MAF, the car turn off). I have changed almost every hose related to air flow and it hasn't helped, the muffler shop check catalytic converter and the result was OK. I have taken it to different shop and they could find the problem
Anyone have an ideas?
