Hi guys,

The check engine light has been coming up on my 2010 VE SS. I had it serviced the other day and apparently it is running lean "bank 1 bank 2". They have told me it needs to go to an auto electrician for diagnosis as he thinks it could be a damaged O2 sensor.

Is this possible?

Cheers

Hmm, How can you have it serviced,
And all of sudden the O2 Sensor activates the MIL,
What else the mechanic do ?

Get a Tech 2 read. Could be a number of things.

Did you have anything done to the car before the engine light started coming on?

You need to check live data on the front O2 sensors...if the mV needs to be fluctuating between high and low.

Also it will be worthwhile to check spark plugs and get an idea what's happening based on them.
