I had the famous missfire codes.....Replaced all my COP's , & plugs & erased codes.

Took my truck to get it registered & on the emissions test the EVAP & Catalyst is "NOT READY"

I drove it around at 55-65 for about 60 miles, drove it around town & still comes back as "NOT READY"

---what can I do to get these two to pass?

jbrew---thanks for posting that!

I found where you had posted that previously in another thread & have tried both, all of it!

Catalyst & EVAP still show up "NOT READY"

 

Huh, Iduno then, that always works.. -Well it use to, I should say lol.

The monitors are all programmed pretty much the same, from 97-03. Well, if you let it ride, the EVAP should go on it's own fairly quick. If you do any highway driving, the Catalyst will get there, eventually, that one takes awhile unless you run thru the procedure and it works.

Try it again.

BTW- If there's a problem somewhere, you should have a CEL ~ DTC or Pending. Have you done any modifications to the engine/exhaust?

 

I have a flowmaster exhaust, but have never had any problem.
