A freind at work has a Peugeot 206 Sport Petrol 1.4v manual that currently looses power when driving along, and especially at roundabouts she finds it hard to get a biting point and rev's it a lot just to get it going, also the rev counter needle seems to yo-yo between 50 and 1500 rev's.
She's had to have the clutch replaced recently due to this problem.
Note this car has been in/out of the garage for the past 18 months to discover the problem, but to no avail so I offered your brains to see if you can help suggest any remedy's.
