no EML on usually... but this morning it really struggled to get going. it sounded like it was chugging and was seriously down on power... then after a while it got better. it did stall once with the EML light on... but this could be because of the RPM dropping so low it stalled??!!

try doing a paper clip test, it should bring up some fault codes for you...

what you running a dizzy cap or coil pack?

is it missfiring 1st thing in the morning then it will clear and when you use it later it would be okay no problems at all or doesnt it miss fire

remove the fuse box cover on drivers side, and you will see a grey block on the left hand side, get a paper clip and as you look at the block put one end of the paper clip in the top left and the other end 2nd from top on the left. and video recored the eml light flashing it will flash one then stop then twice this just means start of the test it will do that three times then will give you the code by flashes.

as you look at the steering wheel on the right hand side infront of the window winder on the door card, just pull it towards you and the cover will pop off

you could try an old trick i learnt... pull your lead out from sprak plug to coil pack and electric tape it up go up and down it twice, and see what happens.. when i had a misfire in the wet it was the only way i fount out it was the leads. if the coil pack was at fault it would bring the eml light on
