hi everybody,
I have a 97 vt commodore v6 and it has recently dropped a cylinder. When it is idling, it has a slight miss, then in gear it its quite shakey.
When I am stopped at lights there is sometimes a knock, but not always. (only in gear but at a stop)
When I cruise between 1800-2200rpm it shutters badly and i need to keep it in 3rd gear and keep the revs up close to 3000 to keep it from shuttering.
I have changed the leads and plugs, didn't fix it. Changed the leads again to the Blue heavy duty leads... Didn't fix it, Checked the plugs again found cyl no6 very very black so I replaced it and put the gaps to 1.2mm.
I changed coil pack, all the vacuum hoses, cleaned the throttle body, airflow metre, fuel pump and filter cleaned the tank aswell and it is still misfiring and running badly.
When I take the plug off the 6th Cyl it has spark but the car does not react compared to when I take off the 5th or 4th.
Any help on what could be wrong would be awesome and a solution would be even better
Thanks
Anthony
