My sons 2002 ford ranger won't pass emissions. Check engine light is on but when l did the test no codes came up. A while back it came on and it was running lean in bank one. It's a 4 banger so... so far I've replaced the up stream 02 sensor air filter and fuel filter. I'm open to suggestions. It idles a little little rough but it has 220000 miles on it

How about the spark plugs? Doesn't the 2.3L I4 have two per cylinder? I would pull those and make sure they are all clean and in good shape. Maybe use a scanner to "clear codes" anyway or leave the battery disconnected for a while to see if you can get the PCM to forget the code.

It has 4 plugs. I've tried all of the clearing tricks. To no avail

Have you changed the oil recently?

At that age, all rubber lines are suspect. A vac leak will cause a lean condition, as will several other issues.

If you have a CEL, you can pull the code with the proper equipment. This is where I would start.

My understanding is your car's computer has to talk to the State computer, else your results will not have your VIN on the paperwork.

There have gotta be codes.. if they were cleared you have to put a certain amount of miles on it before it will pass....

100 or so will do.
