Problem can't seem to be fixed
Alright so Let me start off from the beggining. A couple of months back I did my spark plugs and my valve cover gaskets. Everything went good and my car was driving better than normal. Suddenly the CEL and the VSC lights come on. It was throwing the code "P0031. Which is O2 sensor. Bank 1 sensor 1" I replaced it yesterday and my ECU restareted but my light came back on after I drove a few miles. I know people say that a lot of times it's not the sensor and it can be something else. What should I check? If not should I go to the dealership for a diagnostics? Emmision are coming up. Thanks in advance

This car can drive like crap if something as simple as the battery post isnt fully tightened or cleaned. Check for an air leak as well near that O2 sensor, leaks are usually 420/430 codes but you never know worth a try. If you didnt leave the battery unplugged for at least an hour or two then you did not recet the ECU, also use the OBD to clear the codes as well.

Well first, did you use OEM denso O2s? You MUST use OEM O2s I can't stress that enough, don't know how many people I've heard of buying those garbage universal ones or some other brand just to have to change them again when they're CEL come backs on again. You should've just changed them all at the same time to avoid this. If you have the money change all the o2s because eventually they're GONNA go bad anyway so your gonna save yourself on labor unless your doing them yourself
