Does anyone know of a garage in Sheffield that can diagnose and fix a problem with a car that runs on both LPG and petrol ?

It seems to be a problem with the mixture / idle speed.

Would be nice if I could find one in the city centre, as I work there so it would be easy to get to in a morning.

Been looking for a while now but cant seem to find one anywhere - any help would be appreciated.

Thanks in advance.

i think there s one half way up rutland road on the right hand side

Have you rung pentagon?

Vauxhall seemed to do more of these vehicles than anybody else, so they should be a good place to start, and there's the choice of two near the city centre :)
