A CEL only flashes when the catalyst is at risk of damage. 90% of the time it is due to a misfire. The guys at AZ are retarded, anytime a CEL comes on, there is a code to be had. It may not be present but it will be in the history. The only time a CEL will come on without a code is when something is messed up with the PCM.
