Default Holley EFI O2 sensor

I believe mine is bad. Previous owner replaced it a few years ago with one from oreillys and said it worked perfect. Of course oreillys is giving me the normal “we can only look it up by car make and model” run around.

Anyone know the part number for a normal auto parts store for them?

If it's a Holley EFI system you should be using the Holley O2 sensor. They are calibrated to work with their ECU's. They have different resistors wired to be matches with their systems. I took the hit bought bought the NTK wideband O2's. They are more moisture friendly. I also believe they have their own plug end on it.
