Yeah I got one... only thing I can think of is O2 sensor. Its in and all but that is the only halfway delicate part I dealt with. I reset the ECU and it has gone away temporarily. The weird thing is I installed the header last night and drove for 30 mins, no CEL, drove it over to a family thing this morning, no CEL... let it sit for a couple hours, then got back in the car to come home, started it up and there it is. Any sugggestions??

Most likely its the o2 sensor. It doesn't come on until after a while. Try resetting again and see if it goes away and stays off.

BTW, I love your car without the cf hood. I think it looks a LOT cleaner :)

make sure u plugged it in right if thats good test the o2 sensor if u dont know how to do that let me know ill let u know

Get the code and go from there. I will data log it if you need.

...it's not hard to blow them and since the Sensor just came that is most likely it but definitely pull the code before wasting your money anything

Yeah Brian... I posted on RMDSM as well but i had no luck with trying to pull the code. I reset it and it was fine for a while but it eventually came back. I guess I will see you Saturday... stupid car!!!
