2001 v70 t5 p1171 and p1174
Hello, I just recently acquired a 2001 Volvo v70 t5 and I recently fixed an oil leak a few weeks back and now a check engine light has lit up on my console and upon further inspection there are 2 codes it spat out. P1171 and P1174, with the little research that it maybe one sensor that might be failing (aka MAF sensor) that might be causing the issue. I need some info to see of what the code is actually saying to see what the actual problem is.
( starts up normally and idles at 700 rpm with no fluctuation and only once in a great while from a dead stop the car surges a bit then goes back to normal when accelerating. I can't decide if I have a heavy foot due to not used to the electric throttle or this might be an actual issue)
MAF is running at 4.5 (g/s) on the live data [ its in metric ]
Thank you to who ever responds.

I have a 98, and I plugged it in and looked at my MAF number. Looks like that number is the same. At idle I am running about 0.6 lb/minute which is exactly the same as 4.5 g/s
So if there's no vacuum leak, then it seems to there might be a disagreement between the front and rear O2 sensors. You should be able to see that in live data. Old O2 sensors drift rich.
