I have ARH L/T headers with cats installed. I was doing some data logs and getting what appeared to be off readings. Shaun from AED (as well as others) said the first thing to try was to remove the O2 extensions. (I understand the stock wiring can reach by unclipping the harness from the top of the bellhousing / back of engine.
Can this be done from above the car? After I remove the engine cover and strut tower brace, is it fairly obvious what to unclip? or do I need access to a lift or ramps to go from underneath?
