Hi all I've got Astra J 1.7 cdti recently it has been what I would describe as a misfire but tonight on the moterway on way home from work it started to happen quite regularly and felt as if it was going to cut out it was happening while in cruise control and out of cruise control when It was in cc and losing power it would turn off cc but there is no warning lights or fault codes showing any help would be greatly appreciated someone suggested it could be the fuel pump
Strange one alright. How's the car on idle?
