Ok so me an a friend decided to tear apart the car this weekend and put on a set of BBK LT and a BBK O/R h-pipe without cats. After finally getting everything back together after many choice words....the car is 5x as loud (for obvious reasons i know) and will not idle properly. I know this sounds funny but...sounds like it has a cam now the way the car is rising and dropping in RPM's. It sounds like the ECU is trying to settle itself but cant. The O/R h-pipe has all four O2 sensors in it. I had to fabricate my own extender for the rear O2 sensors. I have already contacted Bama to get my new tune to bypass the sensors but im not sure that this is all the problem. That should just kick a code rite? It also sounds like a drag car when under acceleration. Any ideas?
