Z28ks

Hey guys, recently I picked up a 00 z28 A4 Camaro and changed plugs over the weekend and what I found was disturbing the passenger side plugs are on the right in order. As you can see they are beyond rich and the drivers side on the left look maybe a tad bit lean. The car has Longtubes on it and as you can see from the photos it is a half *** job done by the seller of the car. It seems odd to me to have the drivers side o2 that close to the block only reading 1 cylinder. A list of mods are below any advice or help would be appreciated. I am going to pull the headers and fix the o2's right and need the location of where they need to be. It is throwing no o2 sensor code the only code it is throwing is a P0102 code "Mass or Air Volume Low Input"

Buy some extensions

the sad part is these have extensions on them already. The last owner did this without any research and just put them where he wanted them I guess. Could this be the reasoning behind the plugs? The odd part is the drivers side (JB weld) is the one that appears to be working fine according to the spark plugs. Im puzzled.

have never seen O2 sensors mounted in primary tubes

Very strange from the research I have been getting, I'm going to take the headers off and hopefully be able to tig weld a patch where they used JB.
