i have just purchased a 2002 doblo and it has a few niggy problems just wondering if someone could help,first off on start up the heaterplug light flashes for couple mins,dont no if this is normal or not,2nd this one is quite irratating when changing gears the revs are staying quite high,there is no engine management light satying on or anything and tbh ive never really driven a doblo but it feels quite sluggish as apposed to my brothers scudo which i beleive is same engine,thanks for any help,dave
