I've had an O/R X pipe for over a year, and used MIL elims and never had a SES come on. Last night, however, it came on and was still on today. I ran the diagnostics through the digital odometer while driving the car( http://www.mustangworld.com/ourpics/fcar/dtcodes.htm ) and I noticed the OIL screen came up as 000. (Oil pressure). I came home ASAP and checked my oil, which was at a normal level.
WTF?
