Hi all
I have a VZ Commodore, build date Nov 05
Over the past couple of months the car has become slightly rougher on idle and slightly hesitant under initial acceleration (minor missing)
I could live with this until last week on Idle occasionally the car would miss for a second here and there like dropping a cylinder.
As the vehicle has travelled 130,000k's it was time to bite the bullet and purchase new genuine holden bosch spark plugs and bosch coil packs. I fitted these along with the newer style steel reusable inlet manifold gasket.
After fitting these I am pleased to say the car is quite a bit smoother and more responsive.
I do however still have a problem which is eating me.
The car still has a noticeable intermittent miss on idle but only when in drive and with the aircon on. It appears the more I load the car up (eg air con, high beams) the more frequent the miss is.
I can sit on idle for 10 minutes in park with no air con lights etc and it will purr away.
As soon as I throw into gear it will miss very occasionally but when I activate the aircon it becomes more frequent.
The problem also appears to be more prominent the hotter the temperature gets.
Any help would be greatly appreciated.
Cheers Simon
