Hello, New to the forum.
I have a 2012 Cruze eco 1.4L Turbo that just started running extremely rough all of a sudden and threw a bunch of codes. Vehicle idles and runs very rough, stalls, misfires, sputters, etc.
P0301 - Cyl 1 misfire
P0601 - PCM read only memory (ROM) - checksum failure
P0106 - MAP System performance
P0171 - Fuel trim lean bank 1
P1101 - MAF related?
P0131 - O2 circuit low voltage Bank 1 Sensor 1
When the check engine light first came on it was accompanied by a Traction control/Stabilitrac warning. It got progressively worse over the course of a couple hundred miles until it would barely run.
Car is at the dealer now and all they did is clear the codes and they want to replace the O2 sensor...
I think the most likely culprit is a faulty PCM?
