I have a 2010 Toyota Avensis 1.8 litre car. Problem is that when driving it, the rev counter keeps jumping from 2 to 3 and back to 2. The car makes a revving noise and wants to go up a gear even if I'm doing 60 miles an hour in 6th gear it gives a rev and wants to go up a gear. When I'm driving from 1st to 2nd it's revs and won't accelerate . This is extremely annoying as it nearly got me killed at junctions.
