O2 sensor question for header install
Silly question here, but why does it matter which side the O2 sensors connect to, as long as both front and rear sets go to the same (respective) sides? I ask because I will be FINALLY finishing my installation of the Dynatech kit this weekend (had 2 wisdom teeth pulled Sat. so I wasn't able to finish this past weekend 
) and I realize many "cross" the front sensors and it won't run right. It seems intuitive, because of the way the front sensors are angled, to run them to the "wrong" side and I wondered how the PCM would know if the rears were also run to the "wrong" sides. Doesn't it just compare the front and rear?

I don't know about you but I just hate fixing my car........I love to tinker and make it better, but when it's bad & I have to fix it, well that's a different story.
