Re: 1997 v70r if i (accelerate)hard it loses power

Hi update
Fuel pressure 2.2 bar on tick over
When accelerated it goes 2.8 then drops back to 2 ish
Wen its starts stuttering its at 2ish pressure

Re: 1997 v70r if i (accelerate)hard it loses power

So update
Tcv
Cbv
Leads
Coil
Filter
Plugs
Vacuum pipes
All replaced
And still losing power
If I accelerate hard it goes fast and then just cuts if pedal still down it goes again but then loses power
