Hoping someone may be able to give me bit of advice, When my 95' import is on boost and i get to about 4500-5000rpm turbo seems to stall, car jolts forward but when you come off accelerator and re-apply boost pressure comes back momentarilly until you get to the higher end of the rev range again, problem wasnt to bad at first but now gettin worse been told it may be one of the 4 coil packs? cheers andy

 

could be fuel cut.. do you know what boost it is running?

could be the boost solenoid need a clean..

could indeed be coil packs.. if you are able to reduce the spark plug gaps to 0.5mm and the problem stops then it is spark related and replace the coilpacks.. also inspect the coil packs when you do the plugs as they crack on the ends. You should replace all four at once as they break down over time and should be changed as a set.
