VR running rough after putting extractors on?

Cracked plug 95% ^ I agree, pull them all out and carefully look for cracks, you should see at least one is broken. Just buy another set and be go a bit easier when you put them in this time

There should be a rubber ring that sits inside the sparkplug socket that helps to prevent the above from happening.Remember to keep the wrench straight and inline with the sparkplug ,its the side pressure from a crooked wrench that cracks them.

I saw something a while ago where the leads were losened on the coil pack and then with the engine running, they were removed 1 by 1 until there was no difference in the idle. This would then indicate the faulty plug, lead, coil etc.

Finally got a chance yesty to take out the plugs.
This explains everything...

Replaced all 6 plugs and she runs sweet again =D


Thanks heaps for all your help guys.

try changing your tps sensor mate. its the sensor that is connected to underneath your throttle body that senses how open or closed the butterfly is. should be able to get one from a wreckers for like 5 or 10 bucks. if that doesnt work try your map sensor (the small black box attached to the firewall near your throttle body) and also check out the hose from the map sensor to the throttle body for damage, that can cause similar problems too. good luck mate :thumbsup:
