I have an idea what is causing my car to run like pooh;
-DTC P0121, which is for a bad TPS. I just ordered a new TB to fix this issue.
-DTC P0521 & P0523 are both for Low oil pressure/low oil level/faulty electronics.
I haven't done much to the car lately except an oil change, and the oil level is fine. Could a bad throttle body be causing all of these problems? Could it cause the engine to constantly switch from 4 to 8 cylinders, consume oil & lose pressure? I honestly don't know. But, when driving it does feel like the car is either knocking, switching from 4 to 8 cylinders or shifting. Any help at all will be appreciated. =]
