Well the story begins like this. my cel came on for bank 2 sensor 1 slow response. so i replaced both front sensors thinking it would be nice just to have new in the front. i reset the ecu and 150 miles later bank 2 sensor 1 comes back on slow response. wtf is brand new. so im like alright maybe i got a bad sensor so i swabbed the front ones. and it came back on bank 1 sensor 1. so i assumed that i bought that one bad. before i could replace it the cel light went out. 300 miles later its back on. now it says both bank 1 and bank2 sensor 1's are slow response. wth is going on? what does slow response mean does any1 have a clue how to help me?

do you have an offroad x-pipe? (no cats). If so you need MIL ELIMINATORS, or a tuner to shut the rear o2 sensors off. I had the same problem but now its fixed thanks to the tuner.
I agree with the mil if you have no cats on the x-pipe, but if they do have high flow cats u still might have to get the mil eliminators because even with the high flow cats and your headers your o2 sensors may be setting of red flags in your ecu which would result in poor performance. Even with the stock exhaust system sometimes removing two of the four cats results in the same problem that your having.
i have high flow cats, so i need to buy mil eliminators for the rear o2 sensors? wheres the cheapest place to get them?
There are numerous places that have them for about $50 a set. I got mine from Steeda just because, most places price them within $5 of everywhere else.
