i just installed and ex header on my d16y7 directely to the b-pipe. I was able to attach the first 02 sensor but not the secondmseeing as there is no cat. I didnt get a CEL but when i took it on the highway it started bogging at WOT. When I got off the highway it drove fine again. No clue what this could be. Was thinking about wrapping the second sensor with foil. Any suggestions would be greatly appreciated.

 

anyone?

 

did the bogging only happen at certain rpm's??

 

yeah mainly after 4500 +. Now it also does this when I first start my car and drive then it goes away.?????

 

Buy an O2 sensor simulator.
