[beve1876]

After 2 long runs with the band,i have noticed after driving for 21/2 hrs the van starts to lose power!(feels like it wants to go but cant)wee bit of a hill and the thing is down to 30 mph until you hit a straight then it builds up speed but still feels like its towing a hoose.any ideas??Cheers:)

Have you done the injector leak off pipe mod the return pipe needs swopeing from no 4 injector to number no1 injector to stop air lock in no 1 injector .you need to move the rubber bung from no 1 and put it on number 4 after removing the return pipe this now needs extending and putting on to no 1 injector
