rpms drop video, why?
Hi my friends, i have this issue with my 1996 c220 with a manual transmission. the rpms drop ( as you can see in the video ) to nearly stalling point when i get to a stop.
the car has newer plugs and wires, newer maf sensor, recent oil change and filter and i have cleaned the throttle body as well. how can i fix this problem?
please take a look at the video

With everything you've done, have you checked ALL your vacuum lines for leak?
Visual inspection first for disconnections, cracked or broken lines.

Hi! no vacuum lines or hoses damaged or disconnected. i was wondering if a cheap mad sensor could be the reason, the one i put in may was 43 bucks, i couldnt afford the bosch brand. Mechanic said that some mad sensors replacements act like an emulator because the sensor lacks of a filament, can this be true?

I don't know if it's true, however, it doesnt matter at this junction imho,
ALWAYS, ALWAYS USE OEM BOSCH MAF. PERIOD. Generic MAFS are notorious for creating problems and codes as from many of the members comments across the different MB models.
There is no $aving$ in going non-oem components such as the MAF.
Hopefully, this resolves this for your stalling issue.
