bank 1 sensor 1, p0130, had an ntk, thought it was bad so i got a bosch and it immediately popped the c/e light again this morning!!! someone said i must have an exhaust leak close to or in the manifold, and i looked at the ntk sensor and it was black from only being in for 2 weeks. guess i'm running rich?? i'm checking for exhaust leaks monday, but what else is making this code pop back on?? fyi, the bosch sensor did'nt even keep the c/e light off for 1 day, but the ntk one kept it off for 2 days at a time? suggestions, help. thanks

 

Check the connector and wires. Was this a pnp or did you splice it in?
