Let's face it, the red hair... makes 'em wet.
I had a similar problem. It turned out to be a cracked egr tube between the intake manifold and the egr solenoid, but I think any vacuum leak would cause an erratic idle. What is MODIS? Is that similar to Autotap or EFI-Live?
make sure none of your wiring harness is chafing against something. I hear all the time of misfires being caused by wires chafed against something in the engine compartment. Also check to see that there isn't a broken ground or you have corrosion on the connectors going to the coil packs.

Vacumm leak or fuel pressure maybe.Modis should show you cyl misfire and inj faults.
i try these suggestions and see if these wont work ill hook it up to the big machine

Oh yeah, you sure the connections are good on your wires? I had some pull apart on me... created a SES.
