Ok here is the problem, i have no power above 2500 revs, it will go up to here fine then once it hits that point then it will just stop like it is not getting any pertol. When it is doing this problem it will idle at about 1500 - 2000 revs instead of 500 - 1000 revs. Now this does not happen every time i drive the car and there is no common pattern that makes it do it.
I have had the car services and the mechanics cleaned out the injectors, put a new fuel pump in, checked the fuel pump, changed spark plugs and a heap of other things and could not find anything that is making the problem.
The car is a r32 gts-t (rb20det) with a 3" exausht from turbo and a 5" tip, and a HKS pod filter. Any help would be great as it is making the car so hard to drive.
