I posted a while back about a 1990 Q with a 1995 engine that had bad o2 sensors. Well, I'm now in the process of replacing those sensors and have found that they had been updated about 3 times since 1990 and so I wanted to know if there would be a problem with installing o2 sensors for a 1990 engine into a 1995 engine? For some reason, the right o2 sensor had been updated throughout the US VH45 model run yet, the left side remained unchanged.
