Hi
First of all, I apologize to you for my limited English. I speak very little English.
I am from Guatemala and I have a 2004 Ford Focus Duratec 2.3 PZEV. Everything was working well, but several weeks ago the engine began to hesitate. Then it began to lose power to the point of shutting down the engine (Especially when uphill). I have an Innova 3030 scanner and when I connected it it showed me a P0171 error.
The report that shows me the software of the scanner is the one below this message. Can you help me interpret this report? Could you give me some clues as to why this code is being generated and if the values in the report are normal or are there any that are wrong?.
Here in Guatemala it is not so easy to find a service center that will fix these vehicles well since it is not a vehicle that would have been imported by the distributor. Please help me, I need to repair my car.
Thank you.
