Alright, I'm not sure what all steps to check to try and fix this. Stuck lean code. Car idles on rougher side. From what I can tell, the exhaust doesn't have a leak. Installed new O2 sensors, cleaned filter and MAF. Everything under hood seems to be connected. The intake sounds real ticky but I'm not sure if it's the normal amount or not.

I track the car a lot but change the timing chain setup every second season. Maybe the tensioners? Which o2 sensors did you change, the two front ones are the important ones. The second rear set is for checking the cats and calibrations.

The code is for the primary O2 sensor on bank 2.

Interesting story. When I replaced the 02s the first time, I found out it only has 2 upstream 02sensors. 😅 Hooking up my laptop and viewing data, it is running .84-1.11 lambda. Then I noticed that after awhile everything kinda flat lines and I found codes for a lot of modules not responding and ecm not reading.

So now I am wondering if the ECM is bad. The crappy part is that I am 6 hours from home and I don't return for almost two weeks.
