Hi All,
At the moment when I start my engine from cold (3.9 v8) it is really rough, sounds like a missfire, but after a minute or two it is all normal and also runs fine on lpg.
I thought it was the vac pipe from the air filter box, simply because it wasnt connected. So when I re connected the pipe the engine started fine.
It started playing rough again the next day so I checked the ht leads were connected properly and I removed the vac pipe from the air filter box, re connected it again and it started fine.
But it didn't last long, from cold it was miss firing again. So. I have ordered new spark plugs, dizzy cap, rotor arm, and ht leads.
So my question is this. Where does the vac hose go from the air box filter. I want to remove it and make sure there are no splits or cracks or blocked.
Cheers
John
