This may be considered normal behavior for a 2005 model, though I think an adjustment of the throttle quadrant (do a search) can help. Usually though just letting the ECU adapt will stabilize the idle enough over time. With the fuse problem you had, the ECU might be 'relearning'. Altitude seems to compound the problem, my hunch is the baseline tune is for sea level and if you're at 6,000 feet, that'll make it just that more challenging for the ECU to idle smoothly before learning. Your engine mods are another factor that will influence learning. Idling fine when cold, then rough when warm, is typical for this learn-related idle problem.

Bottom line is, if all you have is a bouncing idle with an occasional stall, give the ECU a chance to adapt before you do spend any time troubleshooting.
