I just spent almost 1100 getting my converter replaced, both 02 sensors, then other just general maintenance thank god it passed inspection b/c after 2 days my check engine is back on again so I’m so frustrated now it runs great but still after just spending all this money of course I’m concerned any ideas please help oh and it has 203,000 miles

 

have the code(s) pulled? there's more than an o2 sensor that can cause a CEL
