Default 2000 Seville SLS rough idle, etc......
2000 Seville SLS 106,000 miles. rough idle, poor fuel mileage. I have replaced plugs & coil pack. I have the intake off now to change gaskets and plenum. The problem now, no cracks in the plenum. I still do not see anything wrong to cause the problem. Could all this be bad fuel?
