Re: [MBZ] M103 Air Flow Meter Boot

I'll have the lines off, so I figure I can flush them out while they're off the car. Wasn't something on my "to do" list, but it is now. Thanks! -D Sent from my iPad > On Apr 21, 2017, at 8:57 AM, Peter Frederick via Mercedes > wrote: > > Bad injectors will give you

Re: [MBZ] M103 Air Flow Meter Boot

Bad injectors will give you rough idle and mixture control issues. When you replace them, leave the lines off at the injector and crank a bit (watch for spilt fuel, of course) -- crap collects in the lines and you can plug up new ones making them as bad as the old ones! I need to replace the

Re: [MBZ] M103 Air Flow Meter Boot

[MBZ] M103 Air Flow Meter Boot

In anticipation of replacing all of the rubber bits on the 300SEL/M13, I was trying to figure out what I would need for the boot between the air flow meter and throttle valve. It’s not at all what I thought was there… I was looking at some parts diagrams and was confused - I assumed the boot
