Ok so last weekend I put in LG street series long tube headers. On my way home I pulled a code P0155 H C. So I looked around to buy a new 02 sensor. Problem is on my 02 everywhere lists a flat black connector for the front and a square for the rear. The rear is a male plug tho. My 04 has a female square connector on the front. So I bought a rear sensor and spliced in the plug since no one seems to have an adapter that will work.
Anyways all that to say I am pulling codes P0174 HC and P1153 any ideas? Anyone know if there is a male to female adapter for the 02 sensor plugs so I don't have to splice the wires? Thanks
Don't know for sure, but I feel your pain. I have been getting an intermittent P0160 H C code since last April. I haven't replaced the sensor yet b/c I've still got a couple of leaks on the right side (where that sensor's code eminates from). I've tried different clamps to no avail. I'm working with Anthony at LG for a solution. If that doesn't solve the problem, I'll replace the sensor and weld the whole system.
I do love these headers, though. Great power and the sound is sweet with a set of Ti's in the back. I'm gonna subscribe to this thread and keep up with other's responses.
