    It was the power transistor unit (PTU) wanst switching the earth therefore no spark at coil. I thought it was an electrical fault not mechanical, thanks anyway

How is the pressure in the fuel rail? a low pressure will cause erratic firing of the injectors - the further down the rail u get usually the worse the problem. If the fuel filter was not changed regularly or if the vehicle stood for a while, dirty fuel/standing fuel at some time in the recent past, this **** will accumulate in tyhe injectors. To avoid spending a loada cash, swap a few injectors around and see if the problem moves with the injector.

SOURCE: 91 mitsubishi gto has random engine cut out.

Does this car have its original ECU? I ask this because this and a number of early 1990s Mitsubishi cars/truckas had isses with capaciors leaking. In truth I believe it is a matter of when and not if. As the ECU begins to fail the engine can begin to run poorly ( I speak from experience after changing both ECUs in my Montero and my son's Doge Stealth (3000GT) ) I did have an issue too with my son's Stealth running poorly, by good luck I happened to be looking under the hood with poor lighting and noticed a faint blue spark from the wiring leads by the coil after a good look I fould a wire would ground out when the engine was throttled; this caused the engine to torque slightly causing the wire to rub and finally ground out.
I hope this may have helped,
Tom
