#6 cyl dead after ECM replacement - no code
I need help. I'm a magnet for strange and rare problems.
2002 c320t, 211,000mi. I've done all maintenance since 128,000mi.
I keep getting a P2023-004 code for interrupted 02 sensor (pre cat). I've checked all pre heat wires at the 02 sensors and the voltage is the same on each one.
This has been constant through a front SAM replacement, new 02 sensors, and ECM replacement, except, when warm and code cleared, the Check engine light will stay off till the next restart.
