Hi, can anyone help. i have an astra 1.6 16valve w reg. it has the koltec vg392 egi system. the car idles fine in both petrol and gas but when you set off in gas it is very lumpy with no power until about 2500- 3000 revs then it takes off. but then shortly after it switches back over to petrol??? I have done a sely diagnosis with the grey wire and it is coming up with code 44?? Which i cannot find anywhere.
Thanks Kye
