Hello, as mentioned in the title, I have a 2005 1.4 16V car. I've had two problems in the last two months. Both occurred while driving uphill. The car suddenly won't get enough gas and stalls. I try to start it 5-6 times, but it won't start. Then it recovers and I continue. Sometimes, when I'm driving below 2,000 rpm, the car stalls and then starts moving. When I connect it to the computer, it gives an oxygen sensor error, but I'm not sure. Could it be the fuel pump, etc.? Anyone have any experience with it? I'd appreciate it if you could share your experiences and suggestions.
