CEL ON
05 c240. I replaced the battery and did the oil change using moble one 0w40. Soon after CEL came on and read p0131, p0151. I reset the code by disconnecting the battery then CEL came off. Drove the car for two hrs on the hwy it seems fine so far. Whats wrong with it?
CEL will come back on again?
Otherwise whats the best bet?

Time will tell but my guess is no. If it does, verify it's the same code(s) again before troubleshooting.
