Hi guys!
So, my check engine, VSC TRC, VSC OFF and 'skidding' lights came on. While I was just driving along on an ordinary road under ordinary conditions. I got it scanned and it returned only one fault code - "P0420 - Catalyst System Efficiency Below Threshold Bank 1." It was reset, and it came on again after maybe 45 min of driving.
I've got the 2005 Grande, V6. I only bought it last week so I don't know much about the history, but it has 90,000km on the odometer.
So I've read there are a bunch of possible candidates - the actual cat converter, one of the 02 sensors, MAF sensor, injectors, spark plugs, an air leak in the intake or exhaust, a coolant leak into the engine...
Does anyone have any suggestions on where I should start diagnosing / cleaning / fixing?
THANK YOU in advance!
