installed a set of headers this weekend, the install went well
but afterwards the car is running like CRAP.
has a miss.
i go thru and check all the plug wires and plugs ..all is good
After doing some research if the O2 sensors after the cat are crisscrossed put on the wrong side could this cause the problem?
i have a 2000 C5 i could of swore the left O2 (DS) connected to the DS harness and the same for the (PS) right side.
I dont have a service manual YET so i am lppoking for some assistance.
On the factory exhaust the DS O2 sensor wire routes over and hooks into the PS plug. The same for the PS O2 crossing over and hooking to the DS plug. What brand headers did you install? If LG headers then they don't cross.
