I know the P1115 code is "Oxygen Sensor Heating 1 After Catalytic Converter - Above Upper Limit"
But whats that mean, does that mean my O2 is going bad or does that mean my a/f is too lean cause of some other issue like a possible bad MAF or vacum leak?
Anyone else experience these 2 codes at the same time?
About 5 minutes before the CEl turned on, i was in 3rd gear 2700rpm and i slammed my foot on the gas to see how responsive the car is and once it reached about 5300rpm's it felt like i had let go of the gas pedel, then pressed it again... kinda scary, then 5 minutes later the CEL came on. And ever since then, the car has run alittle rough... misfires alittle during idle, acceleration isnt very responsive.
