Hi fellas, my 98 v6 is missing a little under load! When throttling it hard up through the box she missis at a little over 4K revs! Doesnt miss badly, and is a little slugish on the way up! This doesnt affect say to day driving at all but is giving me the hump when I want to drive a bit harder.
Anyone any ideas> has been sudgested that it could be the coil pack? but i dunno! ;) as I aint to familier with the duratec.
Any ideas fellas??

Have something to contribute?

could be many things, when were the spark plugs last changed? incorrectly adjusted or worn plugs can cause similar. I.e if the electrode gap is too big it will miss at high revs.

Could also be the coil pack breaking up, id check the spark plugs first though

Could be the plugs.

Another thing to think about could be the lambda sensor.
I changed the lambda on my Escort when it started missing a little under load and it sorted it right out, only changed it cause it failed on emmisions on the MOT.
