Seafoam problems?

Has anyone had any problems with seafoam missing up their o2 sensor?I have read a lot of threads about this happening.
  • Didn't mess up 02 but did free up some junk and plugged the fuel filter and fouled #2 injector.

    Most people have no problem and like the stuff.

    I do like what it did to carb engine like Generator, runs a lot better IMO.
  • Where did you read those threads.What exactly is happening to mess up the O2 sensors,do you have to replace them?I'd like to know as I use it and want to recognize the problem when it happens.How was the seafoam applied or introduced to create the problem?
