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.

...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.

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.

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.

NAPA sells a reman AFM for $100US. Should come with a warrenty. Might be worth a try.

If it were that easy to work on these cars there would be no r3v.

It's very easy to work on these cars. It's just people do stupid things just because they can. That isn't directed to you.

The fact that the E30 is easy to work on makes it just as easy to screw up. If you think the E30 is hard, try changing the head gasket on a Mk1 Mini. :)
