Hey,
It wasn't the EGR, it was the O2 sensor that was messing with my car. The check engine light came on a few days ago, so I ordered the sensor yesterday, put it on today. Checked the ecu code, and it was the o2 sensor. Put it back in normal mode, and the light went off. Now, the car doesn't run like crap when cold. Hopefully, my mileage will improve, too.
Thanks to all who helped.
Jeremy
