3100 Grand Prix SE Knock Retard

[tblake]

Gentlemen, anyone ever deal with an issue like this?

I thought maybe the 3400 tuners might know more about it than us.

Any ideas if the injectors from a 3800NA would fit in a 3100?

What is the flow rate of the 3100's injectors verses the 3800NA's injectors?

Do you think upgrading the injectors might lower the knock retard numbers.

(I think one of them might be flaking out anyways, the car's missfire count shoots up to about 20 on initial startup)

Any ideas?

Thanks!
