Hey guys sorry to bother every1 but i have a prob i cnt resolve. Was getting tyres the other day whilst waiting for cars too move so i could park my vl turbo stsrted puffing smoke and running rough. I took it home and took 1 injecter plug off 1 by 1 all the plugs made the car idle rougher than normal except for #6 so i swapped the leads and the injecter plug still the same, checked the lead to see if it has spark and all good. So i dont know if it is a dead injector or a dead plug?? Wat is every1's thoughts or has some1 had the same prob?? Cheers Chris....

Swap spark plugs, then pull the injector plugs again. If the problem moves to the other cylinder then its the spark plug, otherwise it's the injector. It could be just blocked. Check the resistance of it.

thankx monstaS4 i brought some new plugs today and runs mint now
