Yea it’s so strange, I was on one bar of gas so I got 30 dollars worth and drove 2 miles to my house. Next day I get the flashing sel, I found that one of my oem intake hoses has a crack around the rubber. I siliconed the seal and disconnected my battery for 10 min. Drove 40 miles with no light on but then it came back except no flashing. It’s been about 60 miles and sel is still on but not flashing. Guess it’s time for the stillen gen 3 intake. I still need to change out my plugs and buy some new 02 sensors just in case.
