Hello,

I have full bolt ons and the car is tuned. I was on the freeway today and was accelerating hard when I noticed the SES light came on for a bit then it when away? Any ideas why? The car has no leaks and the mid o2 sensor has been disabled. Thanks

 

who tuned it?

there are patched that make your CEL flash when it detects certain knock levels

 

I see, so it must of detected some knock. it was tuned at 11 afr across the board. It was a real hot day today, perhaps because of the heat?

 

Something else to check is your oil level. I have seen it on other vehicles. Just because you say you don't have leaks, doesn't mean you are low on oil. just a posibility.
