I think the problem was with the dodgy connections to it (especially the throttle-stop one), rather than the solenoid itself. Either way, cleaning and replacing everything fixed it If this is the case, it basically will NOT idle at all, not "it's a bit shaky".
I'd tempted to say your problems sound more like a vacuum leak Gemma.
May I direct you to the stickied topic at the top of this forum entitled (and I'll emphasise this for the hard of hearing)... 1.4 340 running shakey? READ ME FIRST FFS!
Read the whole thing BTW. Hugh comes up with some good points, but I'm not convinced he's all 100% on the money.
