Ford Focus 1.8 Zetec Year 2000 - Kangarooing! - Ali67

Over the past couple of days when pulling away in first gear the car is kangarooing quite badly.

I previously had a problem with the speedo dropping so we have replaced the VSS, the HT leads and put on a new coil pack. The speedo problem is now sorted but now have this kangarooing problem. Only in first gear though.

Any ideas?
