P0153 code.
Bank 2 sensor 1 slow response. Car throws the code every 200-400 miles or so.
I have a brand new Delco 02 sensor in there and it still throws the code. Exhaust is Jet-Hot longtubes, cats, Borla catback. The whole exhaust is welded except for the clamps from the headers to the front of the Y-pipe (a trustworthy exhaust shop said that part would never leak...are they correct or is it possible?) Rear 02 sensors are deleted. Headers have been on the car about 9 months.
What could cause this?

The car was tuned earlier in the year by NoGo and the A/F was pretty much right on after the fact, maybe slightly rich.
Here's the dyno sheet that shows it (no mods since then.)

Bank two would be on the right side of the car in the header right? and the front 02 sensor is for air/fuel and the back 02 is for after converter read outs and, both will throw a codes if they are bad right? Because my SES light came on for a bad 02 bank 2
Thanks Dan

I do not know about your year model, but I have a 2001 corvette. The rear O2 sensors run at a higher wattage, and they cost more. Because of long tube headers, the front (or Sensor 1 location) O2’s are much farther away from the motor than the stock location. Thus, they tend to heat up and cool off, or they simply don’t switch enough between rich and lean.
Well, somebody figured out that the rear (Sensor 2 location) O2’s utilize a higher wattage. Therefore, they stay hot (i.e. they don’t cool off). The problem is that the plug for the rear O2’s is not the same shape (at least not on my car). The front O2’s utilize a flat 4 prong plug, but the rear O2’s utilize a square 4 prong plug. So, you can purchase two rear O2 sensors. The only differences between them and the front O2 sensors are the wattage used and the shape of the connector (at least that I know of). Remove your existing front O2 sensors, replace them with the two new ones. The only problem now is that the plug won’t fit. Well, LG Motorsports (and maybe others) makes a simple extension/converter that will make convert the square plug into a flat plug.
Does that make sense? You need to buy: 2 rear O2 sensors, 2 converters.
This is what I did, and it seems to work.
Somebody else mentioned in that thread these two replacement O2 sensors as well: Bosch 13111 or the Denso Equiv. I would assume that they both come with the square shaped plug, so you would still need the converters to make them fit a flat plug.
I don’t own an F-body, so my fundamental assumption is that your front O2 sensors have a flat-shaped plug. If it is square-shaped, then you don’t need to buy the converters.

I thought the 02 sensors on the F-body were the same on all four, completely interchangable between front and rear. My rears have been deleted through LS1Edit, and I have a new Delco sensor up front on the side that's throwing the code. I'll look into that.
Worse comes to worse I can switch the driver's side and passenger side front 02s and see if the same code comes back.
