DIY AFM Refurbishment

that's probably why your A/F is all over the place. I'll take an unmolested stock AFM over an "adjusted" one any day. did your old one die or something?

The one that came with the car was trashed. New one costs WAY too much.

I had no choice.. I bought mine used off ebay and the spring was all the way loose when I recieved it.

Yeah that sucks, not even sure if there's a real way around that.

I've told people that a million times, but nobody will ever believe me. same reason I refuse to do the M30 AFM swap...

...good advice falls on deaf ears here on IQLimited. People have the attitude that if something's adjustable then it must be there to be fiddled with.

Well I'm fucked.

Dont do it! Never change the tension of the spring on your AFM. You will destroy the calibration of your AFM. The AFM is laser trimmed to a fine tolerance by BOSCH.

Well I'm fucked.
