yep, 1st time i start the engine in the morning she misses, after a few seconds she's running on all 6, runs perfectly for the rest of the day no matter how long between starts except overnight

plugs aren't very old, ~30,000k, leads ~60,000k, leads seem to fit on plugs ok and secure

i'm wondering if maybe it's coil packs?

haven't pulled the plugs yet to have a look, will when i get time

any ideas?

I would have to say plugs or leads.

You shopuld probably be changing your plugs every 20,000 or so depending on their condtion

Very carefully check the plugs as you pull them out, look for any signs of water :cry:

Yeah my guess would be either fouled plugs or leads in this situation

Water in cylinder would definately foul the plug as to would oil and excess fuel

When you pull plug out check that electrodes are in good shape and not broken off or bent out of shape.
Another thing to look for is any hairline cracks in the porcelin cover of the plug as this will lead to failure.
Also look for any corrosion on tip (water) or black slime (obviously oil), if these are current then you will most likely have a serious problem

If spark plugs look fine then through a multimeter onto your ignition leads and see how there fairing

If all these fail to bring anything up then i would look towards the coil packs but most likely these will be alright and one of aforementioned problems will arise

sometimes a leaking injector can cause this, does it throw out any black smoke? my guesse is the head gasket though
