miles on vehicle and general condition/maintenance history?
often, as a car gets 'middle-aged' some attention to things like throttlebody cleaning, fuel injector cleaner, PCV valve replacement/attention, spark plugs, etc., can be good places to look for minor issues that aren't setting codes. Some people say the TPS on the H6 is prone to being flaky. Probably someone else will have some ideas.
modern front O2 (A/F) sensors can last a very long time on a reasonably well-maintained car. If you have a code set, get the code(s) read and post them here. If possible, get freezeframe data too. The longterm fuel trim numbers might implicate a problem with O2 sensors.
naturally, a car with 180,000 miles is gonna be much more likely to need sensors than a car with 60,000 miles.
