You're saying it stumbles when you let off the throttle? In neutral, deccel in gear, what rpm etc.

not a problem in neutral, haven't really checked the rpms when this is happening, all this started when I took it in for a tune-up a couple of weeks ago.

So what, when you're cruising normally and just let off the gas?

Does it idle rich?

It could just be a slightly rich idle and/or no dashpot.
