Did a swap and got a usdm p28.

Now, i`m getting a o2 heater sensor code, and the engine wont rev over 4000rpms.
Now i got a 1 wire o2 sensor so the code i`m getting is normal. Yes, i could go and buy a 4 wire o2, (should) solve the prob .. but i`m not so sure.

Question is : will an o2 heater sensor code make the ecu run in limp mode and not let the ecu rev normally ... or maybe its just a fucked p28 ?

Dont wanna spend on a 4 wire sensor for nothing.
Thanks guys
