Pre-Cat O2 sensor change pics

Ok this wasn't hard but definitely not fun or easy. Total time was about 1.5 hours. I put my car up on some cheap ramps from harbor freight which gave me about 4" of clearance from my chest.

My advice:

Don't waste your time trying to work around removing the transmission cover (6 screws) the skid plate (10 screws) or the passenger side sensor shield (2 screws).

The driver side is a cake walk and only required the transmission cover off to access the sensors electrical mount.

Passenger side has a shield that will require you to remove everything else to access the mount the electrical plugin sits in.

I'm not sure how bad these look but the carbon build up looks somewhat bad. I only turned over the engine to verify I wasn't throwing any codes.

I will drive it later to see if I can feel a difference.

Haha! Love that.

She is running fantastic. I'm noticing a huge difference in low RPM power. She just seems much more eager to run. I'm not sure if it was the plugs or the O2 sensors because I didn't drive it until they were both done, but wow. It may be in my head but my butt dyno lies to no man. Especially not me

You can see from the link I posted it seems like my engine seems to be running on the rich side as well. Perhaps this fixed or helped that? IDK but well worth the time it required.
