96 850 turbo with codes p0440, p0172 and p0133; replaced thermostat (broken) and reset codes, Any thoughts if they return? Any recommendations for a good fuel injector cleaner?

If the engine was running cold all the time that probably set the fuel codes.
Hopefully they won't come back.

Two kinds of injector cleaner out there.
Cheap: just for maintenance.
Expensive: if you've got a problem or haven't cleaned in a long time.
