I replaced the o2 sensor and the cat converter ( cat was burned in the inside honeycomb) and after never had that problem again.

I'd rather delete it, than replace it.

I know the motor in my car has been replaced but don't know what year d15b7 has the 4 wire o2?

some detailed info would be awesome

I think this is what you're looking for:
