Rich or lean?

[98gtblue]

Changed coil packs to screamin demon ones and regapped spark plugs. When checking spark plugs, the four plugs from the driver side were a brownish color. On the passenger side all had a white almost chalk look to it. The two sides were completely opposite from each other. What does this mean? Driver side: dark passenger side: white. Please help.

The brown plugs on the drivers side are probaly normal. White ones on the passenger side are running lean. You may need a new o2 sensor on the passenger side. Thats the front o2 sensor on the right side.

yea the white isn't good, the brown is ok, you should try some fuel injector cleaner, the injectors on that side could be dirty, otherwise it might be a sensor
