FD3 Auto problem

[A.NUDD]

I have a 93 fd3 auto that has been garaged for about a year and a half due to babies being born. I am gonna have to sell it so I thought I would give it a bit of a run. The problem is it started first time and reversed out of the garage no problem but when I tried to give her a bit of a run the car started jumping and wouldnt pull. It felt like the clutch wasnt biting but just wondered if you guys had any ideas. If not can anyone point me to somewhere in yorkshire that I can take it to get looked at? Thanks
