Hi Guys,

My engine check light popped on the other day randomly after driving for about 20 mins. When I got home I took it for another spin and nothing, but the next day same thing. Since then it just comes on after about 20 mins of driving. Took the car to the mechanic and his replaced the O2 sensor but we are still getting the same issue. Have been told this shouldn't be problem and I may need to put an aftermarket computer in if I want to get rid of the error.

Any body else had this problem or any thoughts on what else to try be awesome!

Car is a EJ8 with a B18CR in it. Only mods are a carbon big tube intake and cat back.

Thanks,
