My 2010 camry engine light came on over a month ago, immediately got the light checked. Came up P0101 Mass Air flow sensor, so I replaced it. Light kept coming back on. So I broke down went to the shop they performed smoke tests, no leaks tightened all the hoses and tested the MAF sensor I put in came out faulty. So got another sensor put in by a shop and they said they cant find anything else wrong. 20 miles later light came back on again, got the code check P0172 too rich in system bank 1 cylinder 1. I've replaced the maf sensor twice, air filter housing and had all hoses and areas inspected no leaks or worn out wires. My last thought is possibly fuel injectors or fuel pressure? And also I'm not 100% sure where the injectors or fuel pressure is located on this vehicle. I need help figuring this out. I cant keep paying hundres of dollars for diagnosis noone can figure out.

Unfortunately, the P0172 code can sometimes be difficult to diagnose. When was the last time you change the spark plugs? If you haven't replaced the plugs, I would suggest starting with that, before the injectors.
