2009 E90 N53 Injector Cleaning And Other Questions

rshah77 · 10-01-2018, 10:08 PM

Hello, So I have the rough idle problem. I have made it go away for a little time but want a solution that is healthy for the engine. I have searched it may be the fuel injectors. I have a BMW 2009 330I 272Hp.

I want to know of two things, can I get away with replacing only one or two or is it best to change all of them to index 11?

Could I simply for a simple fix take them out and give the tip a little clean very gently?

Thank you to anyone who takes to time to answer and help a fella out.

You can take them out and have them cleaned and calibrated by a professional company, it's not that expensive. You will then know for sure if they are working correctly.

Don't try and clean them yourself you may damage them.
