I have a auto light reader, and from time to time when I keep the pedal at a con pressure the meter stops reading, and then the car throws a code. The knock sensor code. And then some of the time the code flags and then the sensor starts acting up. The sensor is about 3 months old. It is a Bosch. Could it be just that bosch can't make an O2 sensor to save there life?? Or is there something else that can be causing this? It really started happening when I installed my headders. Mods are in my sig.

 

I did a search, no luck with finding an answer. Can anybody shed some light on what I should do??
