Well car went into my local mechanic today and the throttle was fixed.

It was the cable that needed replacing so he used a genuine Volvo Item and replaced springs etc.... needless to say the throttle is now feather light and makes driving alot easier.

Deffo the MAF thats gone as he tested a new one on it and it ran like a rocket.
Apparently the car is running on cold start at the moment (according to diagnostics) with fuelling higher than normal (which is obviously down to the MAF).

She has new blood running through her now too which is nice for her

Can't wait for the MAF to be fixed then Its time for some FUN
