Hi Mark...

Now I have just found out that you should wait a few days for the new cat to break in but one would think it may work better then the old one



My go-round with etesting started with some exhaust repairs. After getting the holes fixed, I went back to the test facility, where they told me I should wait at least a week after getting new exhaust parts before doing the test. They suggested that crud left on the exhaust pipe/part surfaces during manufacturing would freak the meters.

Have you ever gotten any numbers out of the ECU wrt engine fuel trim levels?
