Im using a PR4(obd0) ecu, on a b20b motor. My problem is that my CYP sensor inside the dizzy is bad, and it's throwing cel#9, im guessing that the sensor is messed up. I don't know if I should've used any octane or fuel injector bull$hit cleaners or whatever in my gas tank, could that be the problem why my sensor went bad ?

The car idles around 200-500, i tried reseting my ecu but when the car warms up it does the same problem, and sometimes it just shuts off. Replacing the CYP sensor will fix the problem ?

PS: It also bogs, like cuts off in a small mili second after 3.1k rev, and then just launches me back. When the car is cold it runs normal.
