Hello,
My 2008 335i has new coils and NGK iridium-ix plugs. It has 127,000 miles on original injectors. The car has a bit of a rough idle. My question is can these injectors be ultra-sonic cleaned? or Do I need to buy all new injectors and have them coded? I see a lot of the NA guys getting them cleaned but not sure on the direct injection. Cleaning is around $50. New injectors are about $900. Any thoughts or advice here would be appreciated. Thanks.
