1. Is my description of the sensors' waveform in my first post enough to give the slightest indication that any of the three parts is not good and need to be replaced? or should I do more tests before buying/replacing anything?
Do they at least show if my converter is blocked or only low efficiency so I can use some spacers? (I'm in PA, and we just turned red)
2. I did buy this ( $87 with a 25% discount and the guy said either weld it or get adapters and fasteners for about $10) and it says 25K miles catalyst work (or something like that). Does that explain a little the crazy difference in price with the OEM given that the original OEM that came with the car lasted over 150K?
3. Is there anything wrong in only replacing the CAT if it is totally clogged or otherwise just use the spacers method to the sensors and not replace any of the sensors?
4. A professional friend of mine told me that there is no real change in the way the car drives after replacing the CAT and that it is only psychological, but another professional friend of mine told me that a big change will be noticed only if the CAT is currently almost totally clogged, otherwise the spacers are the way to go unless your in the republics of CA or NY. Can anyone agree or disagree to either one or at least give me difference they felt afterwards or the differences in the shapes of the sensors voltages or behavior?
