That seems a bit odd... My first thought is that perhaps you are dealing with two problems:
1) Faulty decoder or decoder install (if not plug-n-play). The bell and horn should not sound like that, especially after a reset. And the speed of the loco should not be affected by sounds being played. Can you try it in another loco, or even just hook it to track power to see if anything is different?
2) Mechanical issues with the drivetrain:
Hope that helps,

Quote:Every now and then the engine will start to run rough and sound like it is grinding and then start running normal again.If you can revert to DC power to check the drive, that might tell you something. One other possibility is something that I noticed with my older sound decoder - for whatever reason, it is somewhat noisy compared to straight DC, and this can be hugely amplified depending on roadbed construction. We have one module at the club that resonates very loudly compared to others. Even the quietest, most smooth running locos sounds as if they are "life size" on that track.
Hope that helps,
