Hello, the end of my vehicle registration is quickly approaching so figured id try and get some help here.
I have error codes P0172 & P0175. I have replaced the MAF sensor, bank 1 sensor 2, and bank 2 sensor 2 but the codes came back after clearing them. Any ideas, from easiest to hardest?
Thanks!

SOLVED! ecm reset to clear fuel trim issues from flex fuel

 

Have you noticed a rattle or ticking sound from the front or rear of the engine? The timing chain guide rails and tensioners will fail. Eventually, your engine will jump time. If it's really bad your pistons will run in to your valves leading to a very bad day.

 

I have but my brother and his boss(both mechanics) claim my sounds not coming from the engine. Iv told them before about timing chain being a common issue. Will have it looked at elsewhere at some point
