...recently I have noticed a slight hesitancy whilst driving MY99 with 50k miles.

The problem occurs more, when the engine is cold but is also becoming progressively noticeable when the engine has warmed up.

The best way of describing the problem, is when I am in 2nd gear driving along at around the 2000-2500 rpm with my foot just slightly fixed on the accelerator the car seems to momentarily loose power.

The problem is that it happens intermittently so sometimes it will happen and other times it will go away! The problem seems non-existent when the Turbo cuts in beyond 3000 rpm's.

Recently the dealer had it on the computer but couldn't discover any faults. The suggestion was to start with the leads then take it from there.

I have since found out that the leads alone will probably cost around £100, so I'm hoping this will solve the problem.

Any other ideas what it could be?
