RPM issue with clutch disengaged
I've been experiencing something that doesn't make a lot of sense. It's been on going since day one but I thought maybe it was relevant to the break in period and maybe it being new and tight. I now have 675 miles on it and it continues to occur. Diagnostics say there's nothing wrong, but something is.
First noticed it when I'm slowing down to come to a stop. I'm down to 15 MPH and press the clutch in as I approach the light. The RPM's drop down to 400 RPM, the engine shudders and it then dies. It frequently drops to about 500 when I press the clutch down, but usually recovers to the normal idle of 800 RPM's. I happens at other speeds and other gears too but it isn't constant at one speed or gear or road condition. Also, while a tech was riding with me after the diagnostics said there was nothing wrong, we were going over an overpass in third gear at 35 to 40 MPH and between 3000 and 3500 RPM. I put in the clutch and it dropped off to below 400 RPM and died.
Has anyone else experienced this at any time? If so, was this issue resolved? If so, what was determined to be the cause?
