hi all,

my X5 2001 4.4i is rough on idle during start and only in the morning prior to engine breakdown because of blown piston ring and ignition coil, engine is now overhauled, changed the gaskets, valve cover & spark plugs but after a month it seems that the problem did not go away and now it becomes worse. diagnosed it with GT1 and got two cylinder misfires #1 & #2 as per pic attached. my cluster doesn't show the 'check engine light' although the GT1 says it's on. is this a sign to change the ignition coils? mileage is bad on this car as it has 312xxxkm on it and more problems keep coming, like i just solved the issue with the 'trans failsafe prog' and now here it goes again. temp here in saudi is 13 C in the morning but it's getting rougher day after day.

your inputs will be highly appreciated.

thanks
