How new are the ignition components? Do you have an adjustable fuel pressure regulator?

That's what bothers me. Just did plugs, wires, cap and rotor last month. Haven't done the fuel filter yet.

No adj. fuel pressure regulator.

Do you have a scanner to hook to it?
How old are the injectors?

It might not be that bad. They might not have had smoothing turned up on the dyno.

Unfortunately there's no way to tell from the printout. If they did have smoothing turned on, that's terrible. If they didn't then that's typical.

Was everybody's sheet like that or was it just yours?

Vader,

I don't have a scanner available to hook up.

I haven't swaped the injectors yet.

Nathan,

It is pretty much typical of the othe ones I saw. I think I can tell where the water pump started to go south on the third pull.

Well, I seem to be over my 5MB transfer limit on Village photo?

Anyway, it's an auto. Here's the link to the numbers:

Have you checked fuel pressure? What about using FP to test if the injectors are still good.

That will be next on my list of thing to do. Right now I've got to deal with the water pump issue.
