I bought an Astra 1.6 twinsport SXI (56 reg) afew weeks ago.

It occasionally jumps back out of first gear when i am waiting at traffic lights and is getting harder to put into first.

Also it sometimes takes its time to turn over, first thing in the morning it's ok it seems to be if I've stopped for up to an hr n then go to get back in it it takes around 5-6 seconds to start up.

Does anybody have any ideas what is wrong with her? She sometimes judders when i set off but I'm assuming thats gettin used to a new car appose to anything being wrong there.

Help and advise would be greatly appreciated.
