hey EAGLEMARK last year your tune did pass on the third try. yes sir it did. but like I said she has been sitting in the garage for a month. unless there is something that can be tuned out with HC or NOX I believe I have something stickin. now I do have a question we haven't hit on.

with the solenoid hit with power and ground and engine at idle----should the egr open up and not quiver as it is doing?
