After a bit of help - my sisters 2002 Corsa 1.0 (3 cylinder lump) has picked up a missfire.
It runs fine for around 10 mins then it looses all power and engine management light comes on. It is literally gutless, I drove it today and it would not go over 40.
I have changed plugs & coil pack and no difference, has anybody experienced this before?
Cheers
Chris
