Hi Guys, driving normally at 60-70 on motorway car seems to lose power and start to slow then picks up again?? This has happened 4 or 5 times now, no warning lights, oil fine, iam confused?? anyone help??

 

Any more info? such as Mileage, transmission, engine size, regular services?

 

Hi apart from sticking it on a bidirectional scanner, (activating modules) could be anything,
dose it slow again on long hills,could be the fuel pump in the tank? on its way out,

(demanding fuel might be the slow down) its shooting in the dark.really...............
