I have a code getting my attention. It is a lean left o2 reading. (freescan)

I'm thinking that where my MAC headers go around the steering arm and come together, there may be a leak and raw air is getting into the exhaust stream. I don't have the exhaust clamp on the headers. (kicking myself in the butt)

I've checked the spark plug wires (new) and don't see any arching, plus the car runs fine so it isn't misfiring.

I also saw on my o2 volts L is staying around or below .280 . The integrator is as high as 198 (I think) and doesn't get low up until I get on the gas pretty hard and then it will come down to @ 170.
(which is ugly)

I checked all the plug ins to the injectors and they are working fine, so it's not them.

I also checked the wires comming out of the O2 sensor, and they are fine also. The plug for the o2 pigtail was fully inserted also.

If yall have any ideas, shot me a suggesion. I'm going to put a clamp with some RTV bronze (gold or brown, whatever it is) on it and see what that does.

Thanks
