hey all.
first off,sorry if this has already been ask'd,my vs v6 has been playing up lately,i'll be driving along and all of a sudden the engine light will come on,motor will lose power,but if i put my foot down it fires straight back up.sorta like it coughs and shutters,first real worrying thing that's happened to it.only happens now and then.thought it coulda been the fuel pump,changed that..still dose it.any advice would be great.thanks

Spark plugs and leads?

First thing is to do a fault code check: Checking error codes VR/VS (Revised)

Other possibles are loose/corroded battery terminals or the main cable at the back of the alternator failing....both these can cause you problem and are easy to check.

thanks guys..plugs are about a month old,but the leads are aftermarket bosch leads,that have been on there a while,i'll swap them and see what happens.any other suggestions?

DFI,Coils and it still could be a faulty plug

check fault codes and check back that will help point in the right direction without pending unnecessary money on things that arent needed. but if you want to play the guessing game. maybe the alternator. as once you get that belt moving she fires up again. but that may not trigger the engine light. bit of a mystery until you get back with error codes.
