I have started getting weird increases in rpm. It's usually in 3rd, 4th and 5th. Haven't tried 6th. What happens is when I accelerate sometimes the rpm rises from 2500rpm to 4000rpm as usual then the rpm shoots up from 4000 to 5500 very quickly but the car doesn't accelerate as fast as the rpm does. If you know what I mean. Other times it runs through the full rpm range as it would normally do, all the way to 6500rpm It almost feels like the clutch is slipping, could this be the case? If so wouldn't it happen on every pull? Any ideas on what could be causing this to happen. Could I log anything in vcds to see what is happening, if its ecu related?
