I have a VS 5.0 that 3 of the 8 injectors seem to not be firing and staying open. I have had a new computer installed and still no go. Its basicly undriveable as it randomly loses all pressure and starts blowing out white smoke with a horrible smell of unburnt fuel and runs very very rough. If I play around with the leads n give it heaps it starts to come good but not for long.
tried swapping the injectors around, you may have to replace them then if there still not firing.
I dont think its your injectors,Id be looking elsewhere.Plugs,leads,distributor cap or rotor button.Checking error codes VR/VS (Revised)Check for error codes as well.Just to make sure everything is ok.
