Hi, I'm new to this forum, I hope you can all help me-I'm at the end of my tether with my vectra!! I only got it 4 weeks ago. It's been cutting out when slowing down and revs are low, eg. When I put my foot on clutch to change gear at roundabout etc. sometimes it will start straight back up, sometimes it won't start at all and sometimes it starts but won't rev when the accelerator is pressed and then it just dies after about 5 secs. If driving on motorway it doesn't cut out due to higher revs but will chug and you can tell if I was driving at a slower speed it would've cut out. I've had 2 diagnostics done on it, 1 was fine, 1 said low voltage to relay (relay "peg" was changed but problem remains). I don't know what else to do!! I've been booked in to have it looked at at a garage on Tuesday but not sure what they'll say with no codes coming up!!! Any help would be amazing!! Thanks in advance!!
