Run Buzz test that will fire all the injectors, and report any codes stored in the IDM, other than that you will need to check the wiring. Usually if the Buzz is firing for all injectors, your IDM will be ok.

What he said and if you haven't done the 50 cent mod yet now would be a good time. Also check the wiring harness above the driver's side valve cover. It has a tenancy to rub on the valve cover.

Did 50 cent mod. Injectors check out ok. Will look for wiring damage. Have rough idle and occasional complete breakdown of engine with CEL and OD flashing . Very rough running on only a few cylinders. Then runs ok.

IDM
Inectors sounded ok. Did get a contribution code for #1 and changed it. Still have same code.
I am away from home for three weeks and don't have data with me.
As I remember it was a P02xx code.
It seems that either the IDM or the wiring has a fault.
