[steverrquattro]

I found this site quite useful when sorting out a couple of RR's that had similar issues to yours.

Fuel lines are all new and it's running a Bosch 044 with new filter so i doubt it's that.

I will put timing on my list.

Maf was brand new and cost me £360! But I'll check pins in the connections and the wiring.

The car didn't put me through the windscreen, it will Rev and boost then struggle high up the Rev range and there after the car wont pull as hard until I turn the ignition of and on again

Hard to tell without pulling the codes but that does sound like a knock sensor. As previously suggested, replace both.

I would imagine that they are in quite poor condition.

Where would be the best place to buy the two knock sensors? Are they both the same part number?

Deos it feel like the revs are climbing then then like a slight pause n carry on?

Not the same PN based on the colour of the end and the length of the cable:

Kind of, it just doesn't pull as hard as it should once it's backed off/limp mode
