Return of the ETS light...........

[ammo1981]

I had the throttle body replaced about 3 weeks ago due to ETS light coming on frequently and engine idling irracticly. Every thing has been fine till this evening. I was driving with Winter mode engaged, then decided to switch it off and immediatley planted my foot down. I was approaching a set of red traffic lights to which i slowed down and prepared to stop. As i came to a standstill the dreaded ETS light came on and the engine was idling very low (low enough to cause a shake inside). I noticed one horrible ponging burning smell inside the car (imagine a sewage works on fire!) It was so bad i had to open the windows. I pulled up to one side, switched off the engine and restarted. The ETS light didnt come back on, engine was idling normally. I continued my journey home. I've driven about 20 miles since then and no problems. Any ideas why this happened?

The smell was the cat, see if you have any long term codes to be read,
