VS running rough, misfiring under load

[Barto76]

Hi all, have a VS V6, was running a little rough and had done everything except replace the ignition leads.

After replacing the leads and it was running beautifully and was the gutsiest it's been for a long time when I planted the foot on the accelerator. This lasted only a couple of days and now it's running like a POS, especially when the revs get over 2000. Any thoughts?

You may have a dead coil.

Buy about 3-4 cans of Carby cleaner. Take the air intake off and spray out inside the throttle. You will see black carbon pouring out. Take off the EGR valve and clean it too. Also, do all the sensors and plugs around this area (also the sensors inside the air intake tube).

It will be hard to start afterwards and will shoot a massive cloud of smoke, but you will notice instant performance. Perfect starting and running.

Do this every 4 weeks for about 6mths.

I'll give that a bash, already put in some of that injector cleaner in the tank to see if that works. It's something to do with the 3rd cylinder, took of the injector lead to that and the idle didnt change. Cheers for the info

Check for error codes.Checking error codes VR/VS (Revised)

You may have a dead coil.

Two dead coils it was. Seems coincidental that the coil pack experienced problems soon after replacing the leads.

Should there be error codes coming up with that? I kept getting a 12.
