Hi all,customer reports "misfire" at idle at normal temperature .
Though by no means does this "misfire " the idle is not as smooth as one might expect from this engine type. No DTC present gases in good balance,all HT in good condition. The only item that doesn't appear to be right is the crank case ventilation system!
We have had an older version of this engine in last year with a more sever random multiple misfires present,on this occasion the breather system had excessive vacuum,the oil filler cap was very difficult to remove.We re newed the system and fixed the vehicle , now this new vehicle is showing the same excessive vacuum at the filler cap and dip stick,however the system
design is total different so is this normal for this later engine? Regards Nigel.
