Check engine light on a 2000 GT

[GITY UUP]

I've already ordered a new set of MIL Eliminators from Dallas Mustang this afternoon, I'll see if this resolves the issue. I asked one of their reps. if they get many defective MIL Eliminators and he stated that they rarely do, so I think your hunch on my O2 sensors are correct.

The only problem with the Dynochip route is that I'm planning on supercharging the car in a year when my Ford warranty is up and I'll have to send my current chip back to Kenne Bell. Will I be able to send the Dynochip back to Kenne Bell when the time comes? Also, when you order a chip what information does the manufacturer require, do they require a current list of mods (exhaust, gears, etc.) from your car? I'll go the chip route if I have to I guess, I've seen ads that list them for around $200-$300 dollars and they look like they install fairly easy in back of the passenger side kick panel. Who does anyone recommend to buy the chip from? Do you really see any performance gains out of these chips? Thanks again for the info. SLW, you've been a huge help. This board is a great resource.
