Got a 94 3.0 Ranger and it wouldn't pass emissions. High NOX by almost double.Got 190K miles on it. Last tuneup was done at 140K. New plugs and wires. Cleaned up the PVC valve. Has no EGR. Checked vacuum with guage and its right in the middle of the green. Has a lot of local miles. Not much freeway. Seems to run pretty smooth though. Have run low test gas but have been running hitest lately. Bought vehicle new in '94 and I'm an only driver. Any ideas to get the NOX down? Thanks.
