just bought a vauxhall omega 2.5 td gls automatic s reg 1998 can anyone tell me if they are a reliable motor? there is a problem that i am trying to sort out but can not seem to get any where recently i at to change the clocks in the car as the rev counter needle and the speedo clock needle stopped working the speedo needle just kept jumpping abit that side is sorted . but since i have replaced clocks the problem i have got now is that the ignition key will start engine no problem but when i come,s to turning the key to the off position the engine stays running and the alternator light cmes on but once i turn key to on position light will go out i have bought a brand new ignition switch and changed it but it is still the same. mmmm confusing but if i press the break in and then turn the ignition key off the engine will stop. is there anybody out there that can give me some advice it will be very much appreciated look forward to reply.
