Good point too. Maybe the newer cars with the cylinder canceling systems compensate for that in the programing. Im not sure how to counteract for that being a shade tree guy. I wonder if welding the O2 very far upstream would help. If the cylinder closest to the firewall was deadend but the O2 was placed in the area of the 3rd piston it might help. But no guarantees. Its still getting hit with only 3 fires instead of 4 but at least its not 3 fires and a shot of cooler air.
