ok so ive just done the rocker cover gaskets and everything is fine ,, but when the car is cold it seems to run fine when it get a bit warmer it starts to missfire and gets worse the more you drive ... ive had it on a code reader and its cylinders 1 , 3 & 5 that are missing ,,, im off to get some new plugs soon but is there any other reason it could be doing this ???
just baffles me that it runs ok cold but not warm ???
any help would be great
thanks :y

for all 3 on a single side to miss-fire would suggest coil pack problem, i would suggest swapping the coil packs over to see if the fault transfers, BUT not sure you can do that...... need someone else to confirm :y

D'oh, cheers for clearing that one up. :y
Instead i'd take the coil pack out, inspect it. Mind had some burn marks on it :o
If its just the one side, and the plugs are new / clear of oil, would suggest coil pack failure :'(

When my coil pack was giving up, it could be very temperamental - it would go a couple of days, no problems, then it would start missing all over the place. Not had any bother since changing it, and the fault codes have vanished. My problems were caused by water from the scuttle drain filling up the plug wells and eventually destroying the pack. Managed to get a new boxed genuine GM one from eBay for £35 from a guy clearing out old stock - Autovaux knocking them out for £70 ish. :y Good luck! :y

thanks for all your help everyone ,, i shall get some new plugs soon as money is low at the moment lol ,, and if that dont cure it i guess a coil pack is in order :'(
just incase those 2 dont cure it is there anyother things it could be ??
