do you have a chip in your Ecu?is it a pr3 ecu?and no your car will not run different cause for some dumb reason the b16's 2o2 sensors are placed to try and keeping all fuel intake the same so thay have them in ports 1-2 3-4 so if you bridge them the comeputer will never no cause the temps SHOULD be the same comeing for all 4 cambers..to make it short no and if your ecu is chipped then its even better
