I had the O2s replaced with the vette O2s back in oct when the long tubes were installed, but I have noticed about 4 times in the last 2 days a slight drop in rpm down to around 500 and back up to 1000 after a rev of the engine. Ia it web possible that they could be dead already?

I wonder why two of my own vehicles never experienced that? Kinda odd. Not doubting, just find it odd that simply turning the code OFF has eliminated the issue. By the way, my truck has stock, replacement sensors. Car had the rear Corvette sensors only due to length of harness. They didn't act any differently. SLOW, according to datalogs, just like my truck.

I know full well what the sensors job is, been doing this automotive crap for a living for 29+ years, that's why I find it odd that MOST people simply turn off the code and never have a problem, yet some do. Kinda whacky, isn't it?
The only time I have ever fouled out an O2 sensor was with leaded gas. Then and only then have I gotten the crappy idle, crappy low rpm driveability problems like some have described above.
I have no clue about how many frames I log, but can say that I always log a minimum of 30 minutes, which is plenty enough time for me to see what's happening in any situation the car/truck is running in...

Is there another thread about long tube headers and O2 sensors? And, anyone have the part number for the Corvette O2 sensors mentioned in this thread? Or, is there a way to identify what I have in mine?
Al 95 Z28, long tube headers and bogus O2 readings.
