ok pretty sure my cat has gone bye bye. Correct me if I'm wrong but a cat has "honeycomb" shaped cells in it or a sort of lattice right? mine is completely hollow. I pulled the o2 sensor out and looked inside with a flashlight and all I see is a big empty cat, I can see the walls of the cat and the exit hole on the bottom, its not like its been hollowed out, the walls are completely smooth, it seems like its just completely depleted everything inside of it.
Also, I checked resistance on all 4 injectors and they all measure either 12.1 or 12.2 ohms. although they could potentially still be leaking
would not having any backpressure from the cat being hollow cause a false reading from the o2 sensor causing the ecu to dump more fuel?
