ok so i have a 2.2 and one day me engine light came of after i was ****** around in the parking lot on an icy road it was my o2 sensor after the cat so after being lazy ang getting it fixed 4,000 miles later i put a brand new one in whch was better than the first and with every driving so speeding racing or whatever my engine light is on again and the code is the same thing the o2 after the cat....so i have the CA XTC 2.5 DP installed..... the mechanics at my job say its possible the high flow is burning out the sensor and they i should hae them build a custom DP with the o2 farther away, either way the auto store is only gonna replace this one once bc of the 1 year warranty which lasted 72 hours lol.....has anyone had issues what do u guys this i should do? is theis the end of my bolt on performance parts? mabe its time to trade it in and buy the ss/sc...please help
