Missing/Flat around 3krpm

[topcat1]

Hi all, enjoyed a couple of hours driving the Tuscan today, and apart from the heater just blowing warm air (stuck flap I assume?), it developed a bit of a judder when running between 3000-4000rpm. If driving slowly and in a high gear around 2k it's ok, but increase a bit to pootling along at over 3k it is very lumpy and juddery (is that a word?!), but WOT it pulls like a train.

I thought it may be HT leads breaking down, although as it doesn't seem to happen at higher revs I'm wondering if it is play in the throttle spindles?

Any thoughts?

Cheers, TC.

The only thing that made me doubt the ignition system is that I thought it would get worse with more revs? I have a feeling the leads were changed recently too, but will check invoices and probably do them first as dont look new.

Thanks for the replies!
