So one day i got an increased emissions light, and this was the code: I was just cruising when the code popped up




I cleared it and the car has been running good for the past 1,000 miles since, no light... But the code has been showing up when scanning for codes, every now and then.. Doesnt happen consistenly every time i drive the car, only sometimes.
The code says it will give a warning light, but i never get any lights..

I have been running the evolve tune for around 5,000 miles, so i dont think this has to do with anything. Since i never got this code before.
I also have intakes but i dont think that can effect lambda codes.
I have 41,000 miles on the car. Never had any engine issues or codes prior. Run 93 octane but this happened right when temps went to freezing.

Lambda warnings are are usually 02 sensor related. That is where i would start looking although 02 sensors at 41k is quite early i think.

Try resetting DME adaptions and see if it goes away. Looks like your gas could be a bit ****ty, try another gas station.

If all the above fail, buy a new lambda but replace both otherwise you might end up with weird fuel trims.
