1996 R33 Series Ii - Idle Hunting, Spluttering & Stalling Every Gear Change

[Daniel_r33skyline]

I have a 1996 series II R33 skyline (turbo) and it has spent almost 10 weeks at 2 or 3 different mechanics in town to no avail. The car will idle hunt...rev up & down irratically...wont sit on 1000rpm and pure like a kitten unless cold or you sit there and be patient and by luck get it to idle normally. The car stalls at any gear change after its warmed up. It also has nothing from 4000rpm onwards...but from idle to 4000rpm its a rocket...coil problem? AFM has been replaced and the engine is a tank...all tests have been done...compression etc and the mechanics told me that the engine and its components are perfect...the car more or less is a tank a perfect import.....i bought a new Garrett turbo 340hp....car has all other normal mods...run on stock boost. the mechanics have swapped computers with a 32....and all other components. The car was fine til the stock turbo blew which was fine...then upgraded to some monsta 600hp turbo which then was faulty....have bitten the bullet and bought a quality garret turbo run off the stocko manifold. have no ide what to do next....my options are limited.....mechanics have checked everything possible....it has to be something small which i may never find which could cost me a great car.....so has anyone had this before or know what to do next? otherwise my r33 will be used for parts.....
