Well I disconected the EHA valve and it seemed to run a little worse....
Checked the fault codes again after I reconnected the EHA, and nothing showed up.
After that I pulled the OVP relay and it just happens to rattle.... Hmmm.
So I will replace that and then let you know what happens. If that doesn't work I will try the microswitch, as that is the type of symptom it is having. (coughs just at the point where the switch would be actuated) I really can't be certain what the problem is, but I will try all suggestions until I find it!
Oh, and one more thing, I can only get it to rev when I just barely press the throttle.(slow roll-on, about 1/4 of the way) If I mash it, even at 3500, it coughs and sputters.

Thank you, guys!
Nathan
