any updates of takeaway in terms of MAF cleaning? Should we clean it regularly or not? Thanks for sharing.Larz wrote: ↑Fri Dec 19, 2014 3:31 pmI cleaned the MAF sensor on my old M as well. When I did the same thing to my 09 M, I cleaned them both the same way the video recommends and used the same brand MAF cleaner ... but ... after they dried, I forgot to plug in one of the MAFs and that must have thrown the engine into a mad cow state. My idle was near 1,000 instead of 600, the engine was very rough and the CEL switched on. After I fixed my mistake, everything was fine but the CEL did not go out, so I had to do the ECU and throttle resets.
As for the throttle bodies themselves, no I haven't cleaned them. I assume since I have two intakes, I also have two throttle bodies. I have heard the same horror stories. I am taking the car to the dealer for coolant, trans, and diff fluid changes next month so I will have them clean the throttle bodies and fuel injectors at the same visit. They will also be changing the brake fluid when they instal my brakemotive kit ( will be ordering that in the new year). I do the power steering fluid myself using a turkey baster that I commandeered from Fetucini's SPAM tools, LOL.

In this scenario, I might get lucky that contamination is throwing the code.
If not, nothing lost except the money spent on MAF sensor cleaner!
Caution with using MAF cleaner:
Less is more effective, do not drown out the sensor & use up the can on it!
Reason is any wet residue that might not evap could destroy a good sensor.
If you decide to clean it, let it dry thoroughly before re-install & start up.
