Give us more details.

Do you still have the stock electronics?
What batteries are you using?

You said "recently", so it ran fine in the past? is this a new engine or used? Either way just go back to the stock settings and go from there. You generally want to set your HSN first to get it running and moving. Then you can set your idle and LSN once its warmed up.
