I've had a search and seen a few similar things with other Panda's, but all seem to happen under circumstances different to this, so thought I'd start a new thread.

Sister moaned the other day that her car (2004, 1108cc Active, 48k on the clock, serviced last at 43k by myself) is randomly juddering in 5th.

I had to pick her up from one of her nights out tonight and so took her car to see what was happening.

TBH got nothing on the way to get her as was driving rather enthusiastically

On the way home though, low and behold there it is. Not only in 5th, but 4th also.

It doesn't happen when accelerating, or changing gear, only when cruising at a steady speed can you feel it.

It's not violent, or really that bad tbh, just annoying. It's not like a mis-fire per say, but does feel like there is a fuel issue etc.

No MIL, and checked coil packs and HT leads and they seem to be ok.

Any idea's?

I'm planning on doing a live data run at somepoint, to see if anything grabs my attention.

Pretty hard one to diagnose this one..but sort of sounds like a fuel issue to me..fiat did do some ucu updates on the panda so that might be a good place to start..I would run some injector cleaner through the old girl incase the injectors are getting blocked up and see where it goes from there..
