The other week I was constantly getting code p0172 (running extremely rich) and gas was getting Into my oil so I showed my mechanic I work for and he said to get it pro tuned as a fix. Got it pro tuned the same week and a day or two after my fam drops to .925 (or something in the i don’t specifically remember) and I didn’t think anything of it but since it has been constantly dropping and is at .250 I also have noticed a sound when I come towards a stop i here screeching from my breaks (I assume) and took a video of the sound and showed to my mechanic who said it was something to do with the tune. Anyways I’m asking for advice because I daily this car and would like to know any info on what to do and if it’s okay to continue driving my car for now. Anything would be helpful
