Need Help: Ses Light
SES light has come on again. The car was programmed by MTI after header and cam install and threw a code right after the header and cam install. I took it back to them they fixed it and said it needed a new O2 Sensor. I drove it for 2 weeks about 400 miles including a trip from Houston to Austin. The is on again. I tried unhooking the negative battery terminal hoping that would reset the computer and hooked it back up no luck. I don't know what the problem is. I want to know if there are things I can check or something I can do to see if the code will clear. I hope unhooking the battery doesnt delete the MTI program. I guess I can take it in to the dealer here in Austin, Texas and have them read the code. But if it is the 02 sensor again there has to be a problem because not everyone is running through 02 sensors like this. I was thinking about just using 02 sims even though I am running cats. Would this solve the problem? Secondly I have an electic air fuel ratio gauge that is electric and I think it is tied to an 02 sensor is using 02 sims going to have an affect on that.
