Hi all, new member alert!
recently bought my 320i and after a good run on the motorway something has gone wrong, im new to these cars and have no idea where to start
symptoms are... on tick over revs dip from 8000 to 5000 about evry 3 seconds then jump back up again.
very thirsty on juice
when driving under load feels like the engine is missing.
sparkplugs are sooty
and a noticably drop in power
its had a new MAF senser before i bought the car, air filter is reasonable, checked all the plugs for sparking and there all ok.
any suggestions much appriciated!!!!!!!!!!!!!
