Opel Vectra 2.0L 1994 starting problem - NewZealander
The problem with my car is that after I have driven it for 15 minutes or more, and the engine warms up, i get troubles.
If I stop it for about 5 minutes and then start it again, it turns over, but wont ignite, so I put the accelerator down and it normally gets going, but I have to keep the revs above 1000 or else it will cut out. After I have been driving for about a kilometer it comes right, and it wont cut out on me. By the way it is an automatic so I can ride the brake and accelerator, and I think it is similar to a vauxill in England.

It sounds like the ISCV (Idle Speed Control Valve) is gummed up. Common fault with Vauxhall's of this age.
I've done a quick search for you and found a couple of similar threads that might help.

Not sure if this helps or not?
