Thanks for the reply guys. I don't know what that line is. the car is stock 87. cat sits on top of the muffler, and it is a small diameter pipe that is welded to the cat. I don't think it is the o2 sensor, I thought that was on the other side of the car near the wastegate. Forgot to mention, the only mod the car had when I bought it was an Andial intercooler. Do you guys know if this IC would be adequate, or should I upgrade.
