Strange power problem
Hi guys,
Yesterday, shortly after starting my scooby (RB5) (so it was cold), I noticed that in 3rd gear at approx. 3k rpm the car was sort of lurching back and forth - as though the power was intermittently cutting out and kicking back in every couple of seconds. This only seemed to happen when I remained at a steady 3krpm - accelerating wasn't a problem (no lurching), just when I maintained an exact speed. The problem didn't appear to be there are higher revs either.
Just took him out for another spin this morning and the same thing is happening - at between 2.5k rpm and 3krpm it's still lurching.
It does seem to disappear when the car is warmed up though.
I'll book him into a scooby specialist soon, but just wanted to post to see if anyone had any ideas as to roughly what it might be. Could it be a turbo problem?

Just had a thought - would going from regular unleaded to V-power cause a problem? Would the ECU in an RB5 map itself to regular unleaded?
I ask because the guy before me ran it on regular unleaded, but since I bought it a couple of months ago I've only run it on V-power.
Anyway, any thoughts/opinions appreciated! Cheers guys.

So is this a problem that needs fixing, or just a common issue that won't cause any harm?
Just don't want the car to clap out on the motorway!
Cheers
