[José Paulo Gonçalves Pereira]

Hello to all.

I'm a newbee.
I've joined this mailing list because because I have a problem with my car that no one can solve.
I've a 1994 Opel Corsa Gsi16V with the C16XE engine.
The problem is that the engine as an hesitation when reaccelerating.
With half charges in the gas, the engine doesn't seems to work normal.
There is a lot of people that suspect from the EFI.
Does anybody as any idea what this could be?

Thanks for all the suggestions.
